Which organism in this food web has the greatest influence on the ecosystem?

I think that the plants in the food web have the greatest influence on the ecosystem because they produce energy for most of it.

What organism has the greatest influence on the ecosystem?

Producers because they directly control the numbers of other organisms in the ecosystem. The food in an ecosystem (wether the producers or the prey) directly control the numbers of the trophic level above them. The producers must be the biggest because they provide the energy for all other levels.

Which organism is the most important in a food web?

The most basic trophic level is producers—plants such as underwater bay grasses and free-floating algae that make their own food through photosynthesis. Producers are the basis of all food and influence the production of all other organisms.

Which organism will have the greatest effect on the food web if it were removed?

Removal of organisms at “the bottom” of the web would likely affect it most, as they provide the greatest amount of nutrition for the overall web. Removal of the ultimate predators at “the top” of the web would likely affect the web the least.

What is the example of a food web?

eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal. The snake may eat a beetle, a caterpillar, or some other animal.

What organism is missing from this web?

What two types of organisms are missing from the food web? One group of organisms that is missing are the producers, plants and other photosynthetic organisms.

What is the important of food web?

Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.

Which of these animals would be placed highest on the food chain?

At the top of the scale are meat-eaters that don’t have any predators themselves, such as polar bears and orca whales. Instead, we sit somewhere between pigs and anchovies, scientists reported recently. That puts us right in the middle of the chain, with polar bears and orca whales occupying the highest position.

Why does organism eat another organism?

A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.

Which organism will affect the food web the least if removed and why?

The member of the ecosystem which would affect the food web the least if removed is the apex predator.

Which organisms should be the most common in the ecosystem in order for every organism to get the energy it needs to survive?

The most abundant organisms in any ecosystem, aside from the decomposers, will be the producers. Plants have the most energy available to them because they trap it directly from the sun. There will be fewer carnivores and even fewer top carnivores.

What are the effects of changes in the food web?

Effects of climate change on the food-web structure can have large consequences for the bioaccumulation of POPs. These can be bottom-up effects, in which changes in the abundance of primary producers influence the relative abundance of biota at higher trophic levels.

What is a food web in ecosystem?

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

How is an ecosystem different from a food web?

An Ecosystem is defined as the set of elements, living and nonliving, that interact, over time, within a defined locale. A food chain demonstrates one way in which ecosystem elements interact in a systematic manner.

Why are food webs more realistic in an ecosystem?

Food webs are more realistic because they show that the producers are usually eaten by many different consumers and most consumers are eaten by more than one predator. A food web is the natural interconnection of food chains and generally a graphical representation of what-eats-what in an ecological community.
