A food web is more realistic than a food chain for showing the feeding relationships in ecosystems because

Question

A.
producers are usually eaten by many different consumers, and most consumers are eaten by more than one predator.

B.
a food chain only explains why there are more producers than consumers.

C.
a food chain uses only a large sampling of organisms.

D.
it compares the number of consumers to the number of micro-organisms in an ecosystem.

Answer 1

The correct answer is:

A. producers are usually eaten by many different consumers, and most consumers are eaten by more than one predator.

A food web provides a more comprehensive representation of the feeding relationships in an ecosystem because it illustrates the complex interconnections among various organisms, while a food chain simplifies these relationships into a linear sequence. In reality, producers can be prey for multiple consumer species, and consumers can be preyed upon by multiple predator species, making the food web a more accurate depiction of ecological interactions.
