Most corals, like other cnidarians, contain a symbiotic algae called zooxanthellae, within their gastrodermal cells. In return, the algae produce oxygen and help the coral to remove wastes.
Do Coral reefs help us breathe?
Coral reefs are important in determining the amount of carbon dioxide in the atmosphere. However, both the coral polyps and the zooxanthellae must also use oxygen through the process of respiration (the same process humans use in breathing). Respiration releases carbon dioxide into the ocean and atmosphere.
