What nutrients do coral reefs provide?
Zooxanthellae are photosynthetic algae that use light as an energy source. They metabolize Carbon Dioxide, Nitrogen, and Phosphorus, which are waste products from the coral. In return, the Zooxanthellae provide the coral with their photosynthetic by-products, all of which are coral nutrients: Carbohydrates.
