They consist of individual polyps that get together and build reefs. Significance Coral reefs support a wide range of species and maintain the quality of the coastal biosphere. Corals control the level of carbon dioxide in the water by converting it into a limestone shell. If this process does not take place the amount of carbon dioxide in the ocean water would increase significantly and affect ecological niches general knowledge refresher buy.
