Question

the diagram below shows an energy pyramid. in a marine ecosystem, algae carry out photosynthesis. barracuda eat snapper fish. reef sharks eat barracuda. which organism would be at the top of the energy pyramid? algae barracuda reef shark snapper fish

Explanation:

In an energy pyramid, energy decreases as you move up. Producers (like algae) are at the bottom. Consumers that eat other consumers (higher - level predators) are at the top. Reef sharks eat barracuda (which are themselves consumers of snapper fish). So reef sharks are the top - level predators in this food chain.

Answer:

reef shark
