Food Chains

2. In constructing a simple aquatic food chain, a student lists algae, a small fish, water, and a larger fish. How should these elements be arranged to correctly represent the flow of energy?

• water --> algae --> small fish --> larger fish

• algae --> small fish --> larger fish --> water

• larger fish --> small fish --> algae --> water

• small fish --> larger fish --> algae --> water
