Explanation:

A food chain is a linear sequence of organisms where each is eaten by the next one in the chain. Here, algae are eaten by a small - fish which is then eaten by a large fish, forming a simple linear sequence. A food web is a complex network of multiple food chains. Pyramids of numbers and biomass represent the numerical or biomass relationships among trophic levels in an ecosystem, not a simple feeding sequence.

B. food chain
