Tropical Coral Reefs.

What is the coral reef system?

The Coral Reef ecosystem is a diverse collection of species that interact with each other and the physical environment. The Sun is an initial source of energy for this ecosystem. Through photosynthesis, phytoplankton, algae, and other plants convert light into chemical energy. As animals eat plants or other animals, a portion of this energy is passed on.
