What is a food web?

• A linear sequence of organisms where each is eaten by the next one in the chain

• A complex network of interconnected food chains in an ecosystem

• A diagram showing the energy flow in a single food chain

• A representation of the trophic levels in a single food chain

How does energy flow through a food web?

• Energy is recycled and reused by all organisms

• Energy flows in a circular pattern

• Energy flows in one direction from producers to consumers

• Energy is lost and gained equally at each trophic level
