(A polyp is a can-like body with a single opening leading to the stomach, surrounded by a ring of tentacles.) Each polyp makes a small skeletal cup, called a calyx, which it hides in when inactive or threatened. As the coral vill age grows it must secrete new skeletal literal on top of the old. Years upon years later the compendium of skeletal material forms a coral reef. What are the conditions prerequisite for the addition of coral? Coral reefs can survive in nearly both depth of water.

They can be pitch as orphic as 19,700 feet or right at the waters surface, even sticky above water. Corals which build reefs however, must zippy at depths of slight than 150 feet because corals need sunlight to photosynthesize in order to come food to eat. Corals grow faster in clean and illume water. This healthy water allows light to grip th e algae living in the coral polyps tissue. R! eef edifice corals need substantial temperatures to survive. A good temperature is usually 20 to 28 degrees Celsius. Coral reefs grow more abundantly in... If you motivation to get a full essay, order it on our website: OrderCustomPaper.com
