Which type of model provides the most complete representation of the feeding relationships within a community?

A) A food web

B) A material cycle

C) A predator-prey association

D) Autotroph-Heterotroph relationship

Correct Answer: Option A – Food Web

Food webs represent the feeding relationships in an ecosystem. Hence, Option A is the correct answer.

A predator-prey relationship and an autotroph-heterotroph relationship are only a part of the food web. Hence, options C and D are incorrect.

Material cycle represents the flow of elements such as carbon, nitrogen, etc; it is not directly related to the feeding relationships. Hence, Option B is incorrect.
