DOK Level 1: Recall

What is the difference between a food chain and a food web?

• A food chain is a complex network, while a food web is a simple linear path.

• A food chain shows one path of energy flow, while a food web shows multiple paths.

• A food chain includes all organisms, while a food web includes only producers.

• A food chain is only found in aquatic environments, while a food web is terrestrial.
