ENCYCLOPEDIC ENTRY

A food web consists of all the food chains in a single ecosystem.

A  food web   consists of all the  food chains in a single  ecosystem . Each living thing in an ecosystem is part of  multiple   food chains . Each food chain is one possible path that  energy  and  nutrients may take as they move through the ecosystem . All of the interconnected and overlapping food chains in an ecosystem make up a food web . Trophic Levels Organisms in food webs are grouped into categories called  trophic levels . Roughly speaking, these levels are divided into  producers (first trophic level ),  consumers , and  decomposers (last trophic level ). Producers Producers make up the first trophic level . Producers , also known as  autotrophs , make their own food and do not depend on any other organism for nutrition. Most autotrophs use a process called  photosynthesis  to create food (a nutrient called  glucose ) from sunlight ,  carbon dioxide , and water. Plants are the most familiar type of autotroph , but there are many other kinds.  Algae , whose larger forms are known as  seaweed , are autotrophic .  Phytoplankton , tiny organisms that live in the ocean, are also autotrophs . Some types of  bacteria  are autotrophs . For example, bacteria living in active  volcanoes use  sulfur , not carbon dioxide , to produce their own food. This process is called  chemosynthesis . Consumers The next trophic levels are made up of animals that eat producers . These organisms are called consumers . Consumers can be  carnivores (animals that eat other animals) or  omnivores (animals that eat both plants and animals). Omnivores , like people, consume many types of foods. People eat plants , such as  vegetables and fruits . We also eat animals and animal products, such as meat, milk, and eggs. We eat  fungi , such as mushrooms. We also eat algae , in  edible   seaweeds like  nori (used to wrap  sushi  rolls) and  sea lettuce  (used in salads). Bears are omnivores , too. They eat berries and mushrooms, as well as animals such as salmon and deer. Primary consumers are  herbivores . Herbivores eat plants , algae , and other producers . They are at the second trophic level . In a  grassland   ecosystem , deer, mice, and even elephants are herbivores . They eat grasses,  shrubs , and trees. In a  desert   ecosystem , a mouse that eats  seeds and  fruits is a primary consumer . In an ocean ecosystem , many types of fish and turtles are herbivores that eat algae and  seagrass . In  kelp forests , seaweeds known as giant kelp provide shelter and food for an entire ecosystem .  Sea urchins are powerful primary consumers in kelp forests . These small herbivores eat dozens of kilograms (pounds) of giant kelp every day. Secondary consumers eat herbivores . They are at the third trophic level . In a desert ecosystem , a secondary consumer may be a snake that eats a mouse. In the kelp forest , sea otters are secondary consumers that hunt sea urchins . Tertiary consumers eat the secondary consumers . They are at the fourth trophic level . In the desert ecosystem , an owl or eagle may prey on a snake. There may be more levels of consumers before a chain finally reaches its  top predator . Top predators , also called  apex predators , eat other consumers . They may be at the fourth or fifth trophic level . They have no natural enemies except humans. Lions are apex predators in the grassland ecosystem . In the ocean, fish like the great white shark are apex predators . In the desert , bobcats and mountain lions are top predators . Detritivores and Decomposers Detritivores and decomposers make up the last part of food chains . Detritivores are organisms that eat nonliving plant and animal  remains . For example,  scavengers such as vultures eat dead animals. Dung beetles eat animal  feces . Decomposers , like fungi and bacteria , complete the food chain . Decomposers turn  organic wastes , such as  decaying plants , into inorganic materials, such as nutrient -rich soil. They complete the cycle of life, returning nutrients to the soil or oceans for use by autotrophs . This starts a whole new series of food chains . Food Chains Food webs connect many different food chains , and many different trophic levels . Food webs can support food chains that are long and complicated, or very short. For example, grass in a forest clearing produces its own food through photosynthesis . A rabbit eats the grass. A fox eats the rabbit. When the fox dies, decomposers such as worms and mushrooms break down its body, returning it to the soil where it provides nutrients for plants like grass. This short food chain is one part of the forest 's food web . Another food chain in the same ecosystem might involve completely different organisms. A caterpillar may eat the leaves of a tree in the forest . A bird such as a sparrow may eat the caterpillar. A snake may then prey on the sparrow. An eagle, an apex predator , may prey on the snake. Yet another bird, a vulture, consumes the body of the dead eagle. Finally, bacteria in the soil decompose the remains . Algae and plankton are the main producers in marine ecosystems . Tiny shrimp called  krill  eat the microscopic plankton. The largest animal on Earth, the blue whale, preys on thousands of tons of krill every day. Apex predators such as orcas prey on blue whales. As the bodies of large animals such as whales sink to the seafloor, detritivores such as worms break down the material. The nutrients released by the decaying flesh provide chemicals for algae and plankton to start a new series of food chains . Biomass Food webs are defined by their  biomass . Biomass is the energy in living organisms. Autotrophs , the producers in a food web , convert the sun's energy into biomass . Biomass decreases with each trophic level . There is always more biomass in lower trophic levels than in higher ones. Because biomass decreases with each trophic level , there are always more autotrophs than herbivores in a healthy food web . There are more herbivores than carnivores . An ecosystem cannot support a large number of omnivores without supporting an even larger number of herbivores , and an even larger number of autotrophs . A healthy food web has an  abundance  of autotrophs , many herbivores , and relatively few carnivores and omnivores . This balance helps the ecosystem maintain and  recycle   biomass . Every link in a food web is connected to at least two others. The biomass of an ecosystem depends on how balanced and connected its food web is. When one link in the food web is threatened, some or all of the links are weakened or  stressed . The ecosystems biomass   declines . The loss of plant life usually leads to a decline in the herbivore population, for instance. Plant life can decline due to  drought , disease, or human activity. Forests are cut down to provide  lumber  for construction. Grasslands are paved over for shopping malls or parking lots. The loss of biomass on the second or third trophic level can also put a food web out of balance. Consider what may happen if a  salmon run  is  diverted . A salmon run is a river where salmon swim. Salmon runs can be diverted by  landslides and  earthquakes , as well as the construction of  dams and  levees . Biomass is lost as salmon are cut out of the rivers. Unable to eat salmon, omnivores like bears are forced to rely more heavily on other food sources, such as ants. The area's ant population shrinks. Ants are usually scavengers and detritivores , so fewer nutrients are broken down in the soil. The soil is unable to support as many autotrophs , so biomass is lost. Salmon themselves are predators of insect larvae and smaller fish. Without salmon to keep their population in check,  aquatic  insects may  devastate  local plant communities. Fewer plants survive , and biomass is lost. A loss of organisms on higher trophic levels , such as carnivores , can also disrupt a food chain . In  kelp forests , sea urchins are the primary consumer of kelp . Sea otters prey on urchins. If the sea otter population shrinks due to disease or hunting, urchins devastate the kelp forest . Lacking a community of producers , biomass   plummets . The entire kelp forest disappears. Such areas are called  urchin barrens . Human activity can reduce the number of predators. In 1986, officials in Venezuela dammed the Caroni River, creating an  enormous  lake about twice the size of Rhode Island. Hundreds of hilltops turned into islands in this lake. With their habitats reduced to tiny islands, many terrestrial predators weren’t able to find enough food. As a result, prey animals like howler monkeys, leaf-cutter ants, and iguanas flourished. The ants became so numerous that they destroyed the rainforest , killing all the trees and other plants . The food web surrounding the Caroni River was destroyed. Bioaccumulation Biomass declines as you move up through the trophic levels . However, some types of materials, especially  toxic  chemicals, increase with each trophic level in the food web . These chemicals usually collect in the  fat  of animals. When an herbivore eats a plant or other autotroph that is covered in  pesticides , for example, those pesticides are stored in the animal’s fat . When a carnivore eats several of these herbivores , it takes in the pesticide chemicals stored in its prey . This process is called  bioaccumulation . Bioaccumulation happens in aquatic ecosystems too.  Runoff  from  urban areas or  farms can be full of  pollutants . Tiny producers such as algae , bacteria , and seagrass absorb minute amounts of these pollutants . Primary consumers , such as sea turtles and fish, eat the seagrass . They use the energy and nutrients provided by the plants , but store the chemicals in their fatty tissue. Predators on the third trophic level , such as sharks or tuna, eat the fish. By the time the tuna is consumed by people, it may be storing a  remarkable  amount of bio accumulated toxins. Because of bioaccumulation , organisms in some polluted ecosystems are unsafe to eat and not allowed to be  harvested .  Oysters in the  harbor  of the United States' New York City, for instance, are unsafe to eat. The pollutants in the harbor   accumulate in its oysters , a filter feeder . In the 1940s and 1950s, a pesticide called  DDT  (dichloro-diphenyl-trichloroethane) was widely used to kill insects that spread diseases. During  World War II , the  Allies  used DDT to  eliminate typhus  in Europe, and to control  malaria  in the South Pacific. Scientists believed they had discovered a miracle drug. DDT was largely responsible for eliminating malaria in places like Taiwan, the Caribbean, and the Balkans . Sadly, DDT bio accumulates in an ecosystem and causes damage to the environment. DDT accumulates in soil and water. Some forms of DDT decompose slowly. Worms, grasses, algae , and fish accumulate DDT . Apex predators , such as eagles, had high amounts of DDT in their bodies, accumulated from the fish and small mammals they prey on. Birds with high amounts of DDT in their bodies lay eggs with extremely thin shells. These shells would often break before the baby birds were ready to hatch. DDT was a major reason for the decline of the bald eagle, an apex predator that feeds primarily on fish and small rodents. Today, the use of DDT has been restricted. The food webs of which it is a part have recovered in most parts of the country.

Lost Energy Biomass shrinks with each trophic level. That is because between 80% and 90% of an organism's energy, or biomass, is lost as heat or waste. A predator consumes only the remaining biomass.

A Million to One Marine food webs are usually longer than terrestrial food webs. Scientists estimate that if there are a million producers (algae, phytoplankton, and sea grass) in a food web, there may only be 10,000 herbivores. Such a food web may support 100 secondary consumers, such as tuna. All these organisms support only one apex predator, such as a person.

Out for Blood One of the earliest descriptions of food webs was given by the scientist Al-Jahiz, working in Baghdad, Iraq, in the early 800s. Al-Jahiz wrote about mosquitoes preying on the blood of elephants and hippos. Al-Jahiz understood that although mosquitoes preyed on other animals, they were also prey to animals such as flies and small birds.

Nvidia, Powered by A.I. Boom, Reports Soaring Revenue and Profits

The Silicon Valley company was again lifted by sales of its artificial intelligence chips, but it faces growing competition and heightened expectations.

• Share full article

By Don Clark

Reporting from San Francisco

Nvidia, which makes microchips that power most artificial intelligence applications, began an extraordinary run a year ago.

Fueled by an explosion of interest in A.I., the Silicon Valley company said last May that it expected its chip sales to go through the roof. They did — and the fervor didn’t stop, with Nvidia raising its revenue projections every few months. Its stock soared, driving the company to a more than $2 trillion market capitalization that makes it more valuable than Alphabet, the parent of Google.

On Wednesday, Nvidia again reported soaring revenue and profits that underscored how it remains a dominant winner of the A.I. boom, even as it grapples with outsize expectations and rising competition.

Revenue was $26 billion for the three months that ended in April, surpassing its $24 billion estimate in February and tripling sales from a year earlier for the third consecutive quarter. Net income surged sevenfold to $5.98 billion.

Nvidia also projected revenue of $28 billion for the current quarter, which ends in July, more than double the amount from a year ago and higher than Wall Street estimates.

“We are fundamentally changing how computing works and what computers can do,” Jensen Huang, Nvidia’s chief executive, said in a conference call with analysts. “The next industrial revolution has begun.”

Nvidia’s shares, which are up more than 90 percent this year, rose in after-hours trading after the results were released. The company also announced a 10-for-1 stock split.

Nvidia, which originally sold chips for rendering images in video games, has benefited after making an early, costly bet on adapting its graphics processing units, or GPUs, to take on other computing tasks. When A.I. researchers began using those chips more than a decade ago to accelerate tasks like recognizing objects in photos, Mr. Huang jumped on the opportunity. He augmented Nvidia’s chips for A.I. tasks and developed software to aid developments in the field.

The company’s flagship processor, the H100, has enjoyed feverish demand to power A.I. chatbots such as OpenAI’s ChatGPT. While most high-end standard processors cost a few thousand dollars, H100s have sold for anywhere from $15,000 to $40,000 each, depending on volume and other factors, analysts said.

Colette Kress, Nvidia’s chief financial officer, said on Wednesday that it had worked in recent months with more than 100 customers that were building new data centers — which Mr. Huang calls A.I. factories — ranging from hundreds to tens of thousands of GPUs, with some reaching 100,000. Tesla, for example, is using 35,000 H100 chips to help train models for autonomous driving, she said.

Nvidia will soon begin to ship a powerful successor to the H100, code-named Blackwell, which was announced in March. Demand for the new chips already appears to be strong, raising the possibility that some customers may wait for the speedier models rather than buy the H100. But there was little sign of such a pause in Nvidia’s latest results.

Ms. Kress said demand for Blackwell was well ahead of supply of the chip, and “we expect demand may exceed supply well into next year.” Mr. Huang added that the new chips should be operating in data centers late this year and that “we will see a lot of Blackwell revenue this year.”

The comments may ease fears of a slowdown in Nvidia’s momentum.

“Lingering concerns investors had in the short term regarding an ‘air bubble’ for GPU demand seem to have vanished,” Lucas Keh, an analyst at the research firm Third Bridge, said in an email.

Wall Street analysts are also looking for signs that some richly funded rivals could grab a noticeable share of Nvidia’s business. Microsoft, Meta, Google and Amazon have all developed their own chips that can be tailored for A.I. jobs, though they have also said they are boosting purchases of Nvidia chips.

Traditional rivals such as Advanced Micro Devices and Intel have also made optimistic predictions about their A.I. chips. AMD has said it expects to sell $4 billion worth of a new A.I. processor, the MI300, this year.

Mr. Huang frequently points to what he has said is a sustainable advantage: Only Nvidia’s GPUs are offered by all the major cloud services, such as Amazon Web Services and Microsoft Azure, so customers don’t have to worry about getting locked into using one of the services because of its exclusive chip technology.

Nvidia also remains popular among computer makers that have long used its chips in their systems. One is Dell Technologies, which on Monday hosted a Las Vegas event that featured an appearance by Mr. Huang.

Michael Dell, Dell’s chief executive and founder, said his company would offer new data center systems that packed 72 of the new Blackwell chips in a computer rack, standard structures that stand a bit taller than a refrigerator.

“Don’t seduce me with talk like that,” Mr. Huang joked. “That gets me superexcited.”
