When a population of organisms at a low trophic (feeding) level becomes depleted, organisms that are at the top of a food chain are more vulnerable to ecological collapse than those that are at the top of a food web. a. Trueb. False

TRUE.

Explanation: A food chain refers to the feeding relationships between species in a biotic community. In a food chain, the series of organisms is dependent on the next as a source of food.

A food web refers to a diagram showing the organisms that eat other organisms in a particular ecosystem, predators being higher in the web than their prey. In a food web, there's an interconnection of food chains and a graphical representation of what-eats-what.

An organism that feeds at the top of a food chain is more vulnerable to ecological collapse because of the depletion of a particular feeding population than one that feeds at the top of a food web.
