This is a piece of expository writing about coral reefs. I taught it fitting to write on coral reefs because they are so important and are getting destroyed every day. Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. Living coral reefs are the foundation for many marine species

The oceans today are 30 percent more acidic than they were at the time of the Industrial Revolution. This interferes with the way that corals produce calcium carbonate‚ and it becomes difficult to build reefs. Oil spills are a major issue‚ and in recent accidents; ships hit coral reefs off India and spilt oil‚ causing reef damage. Surface currents are more rapid than the currents of the deep sea‚ limiting the ability of the deeper plumes (oil) to spread widely; oil and chemicals will diffuse as

Coral Reefs‚ Our Disappearing Beauty Coral reefs are one of nature’s riches ecosystems with a diverse existence of life which is ultimately quite complex. They are a colorful ecosystem that plays an important role in the marine world and the human world as well. They are home to countless plants and animals‚ a source of food‚ medicines and one of the unique wonders of our world. While they might bring the image of life near a tropical paradise‚ there is much more to the coral reef than

Coral reefs have existed on this planet for approximately 450 million years. They provide an extremely diverse marine ecosystem. (Bellwood and Wainwirght2002) Coral reefs are the largest natural structures in the world and occur in over 100 countries. They are the result of a remarkable relationship between coral animals and microscopic algae. The microscopic algae (zooxanthellae) coverts sunlight and carbon dioxide into oxygen (photosynthesis) and carbohydrates for the coral animals (polyps)

This is a large-scale issue that could have been prevented by a limitation of greenhouse gas emissions. Riegl and

Coral Bleaching Coral reefs deliver ecosystem services to tourism‚ fisheries and shoreline protection and often called “rainforests of the sea”. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. Coral reefs grow best in warm‚ shallow‚ clear‚ sunny and agitated waters. However‚ coral reefs are fragile ecosystems‚ partly because they are very sensitive to water temperature. They are under threat from climate change‚ oceanic acidification‚ blast

value of Coral Reefs to Caribbean society and culture. Coral Reefs are the home of more than one quarter of all known marine fish species and tens of thousands of other species. The Caribbean coral reefs are vital and valuable natural resources that contain a wealth of biodiversity including over 60 species of coral and 1‚500 different species of fish – many of which are found nowhere else on earth. Coral reefs provide both a good and a service to many Caribbean islands. These coral reefs are

* Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. The polyps are like tiny sea anemones‚ to which they are closely related. * Coral reef ecosystems support a variety of human needs. They are important for subsistence‚ fisheries‚ tourism‚ shoreline protection‚ and

Coral reefs have been dubbed the “rainforests of the oceans”‚ because of the rich diversity of life they support‚ as more than one quarter of all marine animals depend upon coral reefs. Coral reefs are also a source of food and income for millions of people. The coral reef ecosystems benefit humans commercially‚ recreationally and environmentally. Without them many tourism based industries would collapse‚ treatments or cures for some illnesses would disappear‚ and the countless organisms they support

Abstract Located in tropical ocean waters‚ coral reefs provide priceless resources to both human and marine life. The leading natural cause of destruction among the coral reefs is global warming. Other natural causes are earthquakes‚ hurricanes‚ cyclones‚ and typhoons. The destruction to the coral reefs from these natural disasters is minimal compared to the dangers caused by man. Man-made destruction has a much wider impact on the health of the coral reefs. This destruction includes over-fishing
