Coral reefs like the Great Barrier Reef are made up of thousands of tiny coral polyps that build on top of one another and stick together with coralline algae. The Great Barrier Reef contains more than 400 different kinds of coral species -- ten times the amount in the entire Atlantic Ocean [source: Sammon ]. In this way, the algae provide food and oxygen (a byproduct of photosynthesis) for the coral, and the coral protects and provides nutrients for the algae. Scientists are working to find ways to protect it. the limestone skeletons of the coral, with optimal growth occurring at 26-27C.

An independent scientific steering committee with expertise in Great Barrier Reef ecosystems and biophysical processes was convened to define operational principles to guide the development of a comprehensive, adequate and representative network of no-take areas in the Marine Park (Fernandes et al 2005). PMC However its colorful plants and there are three different kinds of coral reefs. coral bleaching, whitening of coral that results from the loss of a corals symbiotic algae (zooxanthellae) or the degradation of the algaes photosynthetic pigment. Reef management. 2020 Sep;30(6):e02122. Great Barrier Reef Published as part of the journal Ecological Management & Restoration, on Conserving and restoring biodiversity of the Great Barrier Reef through the Representative Areas Program(RAP). In this essay I will mention two things; facts about coral reefs and why, The name Tubbataha comes from the Samal language meaning long reef exposed at low tide. There is concern that widespread coral bleaching may cause some species to become extinct locally. There are three types of coral reefs: fringing reefs barrier reefs and atolls. It may result from increases in seawater temperature, particularly when associated with elevated levels of solar irradiance (e.g., ultraviolet radiation), or it may be caused by changes in seawater chemistry (e.g., due to ocean acidification or pollution), increased levels of sediment in seawater, or a corals exposure to sodium cyanide (a chemical used in the capture of coral reef fish).
