Coral Reefs .

chromatic take downs be arguably the worlds most fair habitats. coral reefs shed been c solelyed the rainforests of the oceans, because of the large diversity of life they support. Scientists wear non yet finished t alto raisehery the thousands of various species of plants and animals that use or travel in the coral reef. thither are three types of coral reefs: fringing reefs, parapet reefs, and atolls. Fringing reefs are located most up to shore, separated from come by only(prenominal) shallow water. hinder reefs lie furtherther offshore, separated from land by lagoons more than tenner meters deep. Atolls, on the other hand, are formed far offshore and they make a ring-shaped reef that close a circular lagoon. chromatic reefs are the largest biological structures on the planet, with the largest being the Great barrier Reef covering over 2000 kilometers along the east coast of Australia (Focus, 1995). The reef is said to be 500,000 to 2,500,000 age old and is said to be visible from the moon.(Scientif! ic, 1987). There is only one problem with this beautiful structure and that is the carelessness of man. Silt from deforested lands and contamination from crowded coastlines choke them, and overutilisation by coal miners, fisheries, and steady tourists deplete and destroy coral reefs.

There are many more factors which add to the devastation of the coral reefs, which if not halt it will destroy all coral reefs. Corals are animals, not plants, sunlight is the key to their survival. They get out it to power the millions of microscopic algae, called zooxanthellae, that rest in their tissues. The algae provides the corals with have intercourse and oxygen in offspring for raw materials and a legal place to live. This teamwork is what allows the reef to prevail in nutrient-poor tropical seas. This kinsperson is sensitive to such changes in...
