WHAT IS A CORAL REEF. Coral has a symbiotic relationship each gives something to the other and gets something back in return with zooxanthellae microscopic algae which live on coralReferred to as The rainforests of the sea coral reefs harbor a rich biodiversity. Zooxanthellae are single-celled dinoflagellates that conduct photosynthesis.

Paragraph 1 Coral reefs are natural structures formed from deposits of the calcium carbonate secretions of coral a marine animal that lives in colonies. Some live in warm shallow tropical seas and others in the cold. Large reef building colonies graceful flowing fans and even small solitary organisms.

In general coral reefs are grouped into one of three categories atolls barrier reefs and fringing reefs. Fossil records suggest that some of these structures have been around for hundreds of millions of years. The most common type of reef is the fringing reef.

Coral reefs are formed by. Corals are nothing but calcareous rocks formed from the skeletons of minute sea animals called polyps. Each polyp produces calcium carbonate which makes up their skeleton and protects corals internal bodies.

Coral polyps the animals primarily responsible for building reefs can take many forms. A faster evolutionary response than their host. Coral reefs are some of the most diverse ecosystems in the world.

The corals live in colonies fastened to the rocky seafloor. Coral reef is a ridge of rock in the sea formed by the growth and deposit of coral. Atolls are usually easily distinguished because they are modified horseshoe-shaped.

Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks or other hard surfaces along the edges of islands or continents.

Coral reefs are important ocean habitats and offer a compelling case of the risks of climate changeReefs provide a large fraction of Earths biodiversitythey have been called the rain forests of the seas Scientists estimate that 25 percent of all marine species live in and around coral reefs making them one of the most diverse habitats in the world.

In warm shallow seas reefs are built by coral. Carbon dating or carob 14- dating is another method used to analyze the history of coral reefs. Calcareous algae mollusks corals and.

The polyps extract calcium salts from seawater to form hard skeletons which protect their soft bodies. In order to understand how reefs are formed you need to know how coral polyps grow and reproduce. As the corals grow and expand reefs take on one of three major characteristic structures fringing barrier or atoll.

The leading cause of coral bleaching is climate change. This biodiversity makes them a high priority for conservationThe brilliant corals of Sogod Bay above live in one of more than 400 marine protected areas MPAs in the PhilippinesMPAs help to conserve biodiversity by preventing practices like coral harvesting and dynamite fishing. Coral reefs can not only be found in the warm sun-drenched waters of tropical regions they also grow in cold dark waters within a huge geographical range between 55S to 70N.

The zooxanthellae use the waste products of the coral during photosynthesis and the coral can use the nutrients provided by the zooxanthellae during photosynthesis. Each coral reef is made up of colonies of tiny animals called polyps. THe generation times for corals are orders of magnitude greater than those of symbionts so symbionts may show.
