What is the significance of a food web in an ecosystem?

It shows more interactions among a variety of producers and consumers

It demonstrates the competition between different trophic levels

It shows the linear flow of energy in a food chain

It simplifies the interactions between organisms

What is the main impact of removing an apex predator from a food web?

It can lead to excessive population growth of other organisms

It has no impact on the other organisms in the food web

It increases the energy available to other organisms

What is the main difference between a food chain and a food web?

The amount of energy stored in producers

The number of trophic levels in a food chain

How does biodiversity contribute to the sustainability of an ecosystem?

By providing more options for organisms to survive and recover from changes

By increasing the competition between different organisms

By reducing the number of trophic levels in a food chain

By making the ecosystem more vulnerable to changes

What is the relationship between a food web and a food chain?

A food web is made up of multiple food chains that interact together

A food web is a simplified version of a food chain

A food web is a more complex version of a food chain

A food web is a single chain within a food chain

What is the main impact of removing a species from a food chain?

It can lead to excessive population growth of other organisms
