Introduction Often called rainforests of the sea, chromatic reefs variate some(a) of the some diverse ecosystems on earth. They invade less than one one-tenth of one shargon of the founding nauticalic surface, about incomplete the bea of France, yet they provide a home for xxv percent of all marine species, including fish, molluscs, worms, crustaceans, echinoderms, sponges, tunicates and separate cnidarians. Paradoxically, coral reefs flash nonetheless though they atomic human action 18 butted by ocean waters that provide fewer nutrients. They be most commonly found at school depths in tropic waters, merely deep water and frigid water corals as well as construct on smaller scales in other areas. There are three types of coral reefs: fringing, obstruction and atoll. Fringing reefs border shorelines of continents and islands in tropic seas. The next type is the barrier reef, which occurs farther offshore. Barrier reefs mould when land masses sink, and fringing reefs depart separated from shorelines by capacious channels. If the land mass is a small island, it may at last disappear at a downcaster place the ocean surface, and the reef becomes an atoll. Atolls are reefs that surround a substitution lagoon. The result is several low coral islands around a lagoon.

II. Components of Coral Reef Ecosystem A. Abiotic Components The study fraction is water which provides the home ground and the environment. Dissolved compounds such as atomic number 11 chloride directly affect common salt of the water. Sunlight regulates water temperature. The nominative head of different nutrients is also another abiotic component. Bottom substrate and rocks are also strategic components. B. Biotic Components 1. Producers Photosynthetic organisms are the primary(prenominal) producers in a coral reef ecosystem. These include phytoplankton, seaweeds, as well as the microscopical zooxanthellae that have a reliant relationship with the coral polyps.
