Which of the following best describes a food web?

A food web is best described as a complex network of feeding relationships because it illustrates how various organisms in an ecosystem are interconnected through multiple feeding pathways. Unlike a simple food chain, which depicts a linear progression of energy transfer from one organism to another, a food web encompasses the various diet options and interactions among different species, including producers, consumers, and decomposers. This complexity reflects the reality of ecosystems, where species often have varied diets and interact with multiple other species rather than existing in isolation. Therefore, option B accurately captures the intricate relationships found in food webs, showing how energy and nutrients flow through an ecosystem in a more realistic manner than a simple chain or model.
