Coral Reef Bleaching Coral reefs are by far one of the world’s most productive and beautiful habitats. They also provide billions of dollars in economic benefits each year globally. There are so many different organisms in these reefs that scientists have yet to finish counting them. Corals are having the toughest time trying to survive because of bleaching occurring in the reef systems. Bleaching is a term used to describe the harming of zooxanthalle algae‚ which gives corals their color and

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

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)

atmospheric heat‚ the Arabian/Persian Gulf was inflicted with coral bleaching (caused by detachment of algae from coral due to increased ocean temperature) and disease‚ as studied by Bernhard Riegl and Sam Purkis. This is a large-scale issue that could have been prevented by a limitation of greenhouse gas emissions. Riegl and

ECOSYSTEMS AT RISK – CASE STUDY 2 PART 1: CORAL REEFS – OVERVIEW Coral reefs are often referred to as “the rainforests of the sea” because of they form some of the most diverse ecosystems on Earth. Its massive structure is formed from coral polyps (tiny animals that live in colonies) that support approximately 25% of all known marine species by providing essential habitats. Factors affecting reef development and survival include temperature‚ light‚ sedimentation and salinity of the water. Without

Coral reefs are one of the most biologically diverse ecosystems on earth. They are made up not only of hard and soft corals‚ but also sponges‚ crustaceans‚ mollusks‚ fish‚ sea turtles‚ sharks‚ dolphins and much more. Reef systems serve as barriers protecting many coastal populations and developments from storm damage; they support commercial fisheries; they serve as major tourist attractions; and they hold the possibility of unimagined medicinal compounds in the diverse life forms within them There

* 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

overfishing is affecting corals negatively. This article has also provided me a video interview that was conducted with one of the researchers. Purpose: The purpose of this source is that it provided me more information for my research proving that overfishing contributes to the declination of coral reefs. We need to take action to remove overfishing near these corals because corals are vital to the ecosystem‚ helping us learn the health of the ocean. Taking out fishes near these corals will help algae growth

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

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
