precious precious coral REEFS Almost all bingle of us have heard and most of you have seen the coral reefs exactly did you know what actually these beAs a sea dog its important to know about the marine life, that was one reason I have chosen this topic for my todays short presentation. GM, my system of presentation will be as flashedDEFINATION OF chromatic REEF struggle BETWEEN CORAL AND CORAL POLYPWHERE WE CAN FIND CORAL CONSTRUCTION OF CORAL REEFS CONDITIONS FOR GROWTH OF CORAL REEFSTYPES OF CORAL REEFS THREAT TO CROAL REEFSWHAT SHOULD A MARINER DO IN CORAL RICH AREASFUTURE OF CORAL REEFSCONCLUSIONWhat is a coral reef?precious coral reefs atomic number 18 bulky structures make of limestone that is deposited by living things. There are thousands of species that live in coral reefs, but only a fraction actually produces the limestone that builds the reef. Coral reefs support everyplace 25% of all known marine species. They are one of the most complex ecosystems on the a rtificial satellite, and are home to oer 4,000 several(predicate) types of fish, 700 species of coral and thousands of other plants and animals.A good way to reckon a coral reef is to think of it as a bustling city or community, with the buildings made of coral, and thousands of inhabitants coming and going, carrying out their business. In this sense, a coral reef is like a metropolis under the sea.What is coral?Although coral is often mistaken for a rock or a plant, it is actually composed of tiny, fragile animals called coral polyps. When we say "coral" we are actually referring to these animals and the skeletons they leave behind after they die.Although there are hundreds of different species of corals, they are generally classified as "hard coral" or "soft coral".Hard corals grow in colonies and are the architects of coral reefs. They include such species as brain coral and elkhorn coral. Their skeletons are made out of calcium carbonate (also known as limestone) which is hard and at last becomes rock. Hard corals are hermatypes or reef-building corals and consider tiny algae called zooxanthellae (pronounced zo-zan-THEL-ee) to survive. Generally, when we shed about "coral" we are referring to hard corals.Soft corals such as sea fingers and sea whips, are soft and bendable and often fit plants or trees. These corals do not have stony skeletons, but rather grow wood-like cores for suppor... ...s are considered as part of a larger corner, the recognization of the complexness of environmental stresses can be understood. Management plans can be highly-developed to reduce impacts to mangroves, seagrasses and the reef ecosystem, based upon accurate data and a damp understanding of the system. EPA is in the process of developing guidance for a watershed approach to coral ecosystem protection.CONCLUSIONCorals provide shelter for nearly one quarter of all known marine species. The reefs are home to over 4000 species of fish , 700 species of coral, and thousands of other forms of plant and animal life. Living coral reefs are the instauration of marine life, and this also means that they are essential for human life, but all over the world they are dead or decease because people are destroying them at a very fast rate. already 10% have been lost, and there are predictions that 705 of all corals on the planet will be destroyed in 20 to 40 days unless people stop doing what they are doing now i.e., pollution, sewage, erosion, cyanide fishing, bad tourism.We need coral reefs, and not just to make the ocean look delightful and colourful, they are more than just thateggs.
