By breaking off and making new corals.
No. The coral reef is formed by polyps.
coral polyps and sea plants
no. a coral reef is a colony of many smaller coral polyps. corals are their own type of animal, not sponges.
Polyps
It was created by coral polyps
No, they are made by polyps, which confusingly are also known as coral (but coral the reef is made of and the polyps are two different things).
Inside the Great Barrier Reef are billions of tiny microorganisms known as coral polyps.
They will destroy the Great Barrier Reef and all of them will start to die.
The Pacific Reef is a coral reef located in the Pacific Ocean. The reefs consist of tiny animals called coral polyps. Other animals in this reef include sea anemones, clownfish and algae.
Reef cementing is done by coral polyps whose 'homes' are tiny cavities in the coral that they create.
The Great Barrier Reef was produce by the action of coral. The corals that build reefs are not single organisms. Coral is made up of colonies comprised of many individual animals called polyps, which join together. Coral polyps are a little like sea anemones, having tentacles that extend outwards, but they are not actually anemones. Corals which create coral reefs have a symbiotic relationship with algae known as zooxanthellae. This algae, which lives within the tissues of the coral, causes a photosynthetic reaction which enables the polyps to make skeletons about three times faster in the light than in the dark. This means the corals deposit skeletons faster than the environment can remove it, and these skeletons build upon each other over time, creating a coral reef.
a coral reef is not one big animal, it is a bunch of small coral polyps growing on top of each other. the outer layer are the live polyps (coral is an animal) and they are on top of the dead coral skeletons. a coral polyp does not have a backbone because it is an invertebrate of cnidaria phylum. it has a skeleton made of calcium carbonate, or carbon and calcium. neither one coral polyp has a backbone and a coral reef does not have a backbone either.
