This means that the sea star can be both a decomposer and a secondary consumer. Animals like the sea star can get energy from eating other organisms like clams and oysters, too. The decomposer helps the coral reef because it recycles the dead organisms into helpful nutrients for the environment. The sea star is a decomposer, which means it gets its energy from eating dead organisms. Uh-oh! Do you see the reef shark chasing the parrot fish? A reef shark is a secondary consumer and gets its energy from eating other animals like the parrot fish. The parrot fish is a consumer, which means that it gets its energy from eating producers like algae. Can you think of any other producers? Do you notice the fish trying to eat the algae?
