Question

Quizplus · Accepted Answer

Corals are made up of tiny animals called polyps that have a symbiotic relationship with simple algae called zooxanthellae. The zooxanthellae live inside the polyps and use photosynthesis to produce food for both themselves and the polyps. This relationship is crucial for the formation and growth of coral reefs.
