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 its beauty. These beauties are home to a diverse population that benefits humans, each type in its own way. But will we be able to save these natural wonders? Corals belong to the same group of animals as jellyfish and sea anemones. While …show more content…
They generally grow near the shoreline which is a form of protection for the shore. Coral reefs only grow to depths approximately 45 meters because they need sunlight in order to survive. The amount of oxygen available is also important because coral have symbiotic relationship with some types of algae. The algae live in the coral and perform photosynthesis which makes food for the algae and the coral alike. The coral gives the algae protection and sunlight. For this reason coral reefs are built in shallow, clear water where lights can reach them. The amount of sedimentation mud be low because sediments can block the sunlight they …show more content…
Each of these is thought to be a stage in the development of the coral reef. (Birkeland, 1997). These include the fringing reefs, barrier reefs and atolls. Some scientists include a fourth type, the patch reef, as well. The most common type of ref is the fringing reef. Found very near to land they can often form a shallow area in the lagoon. When reefs are formed it is the fringing reef that is formed first. Another type of reef is the barrier reef. It can resemble the fringing reef but they do not form so close to shore and are usually much larger than the fringing reef. The fringing reef grows out and the distance from land becomes greater causing the fringing reef to become a barrier reef. The atoll is shaped like a horseshoe or can be a circle. It surround the lagoon although there is no land associated with the atoll. This is because when the land subsides, only the reef remains and it has the shape of the land it surrounded. Finally, there is the patch reef which usually are found within the lagoon and ore the outcrops of
