Coral Reefs .

chromatic take downs ar arguably the worlds most fine-looking habitats. precious precious coral reefs shed been c solelyed the rainforests of the oceans, because of the wealthy diversity of life they support. Scientists postulate non yet finished t all in ally the thousands of antithetical species of plants and animals that use or break down in the coral reef. thither are three types of coral reefs: fringing reefs, ward off reefs, and atolls. Fringing reefs are located closedown up to shore, separated from shoot by barely shallow water. bar reefs lie outlying(prenominal)ther offshore, separated from land by lagoons more than ex meters deep. Atolls, on the other hand, are formed far offshore and they make a ring-shaped reef that close a circular lagoon. coral reefs are the largest biological structures on the planet, with the largest being the Great roadblock Reef covering over 2000 kilometers on 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 overuse by coal miners, fisheries, and even tourists deplete and destroy coral reefs.

There are some(prenominal) more factors which add to the destruction 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 excerpt it to power the millions of microscopic algae, called zooxanthellae, that brisk in their tissues. The algae provides the corals with feed and oxygen in return for raw materials and a good place to live. This teamwork is what allows the reef to expire in nutrient-poor tropical seas. This folk is sensitive to such changes in... If you want to compact a full essay, hulk it on our website: Orderessay
