Answer 1

A coral reef coral reef is an underwater structure made of calcium carbonate secreted by corals. It is a type of biotic reef formed by colonies of stony corals, which generally live in marine waters that contain few nutrients. Stone corals are marine animals that consist of polyps, grouped in various forms according to the species, and resemble sea anemones, with which they are related. Unlike sea anemones, coral polyps of the order Scleractinia secrete carbonate exoskeletons that support and protect their bodies. Coral reefs grow best in warm, shallow, clear, sunny and agitated Because of its strategic location between the coast and the open sea, reefs serve as a barrier that protects mangrove and grassland grasses against swellings; Mangroves and grasslands, in turn, protect the reef from sedimentation and serve as breeding and breeding grounds for many of the species that form part of the reef ecosystem.
