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.
The correct term is "coral reef." Coral reefs are formed by the accumulation of calcium carbonate skeletons secreted by coral polyps over time.
Coral reefs are formed by colonies of coral polyps that secrete calcium carbonate to build a hard exoskeleton around themselves. Over time, these skeletons accumulate and create the structure of the reef.
When coral polyps die, their hard outer skeletons remain intact and empty, resulting in the formation of coral reefs. The decomposition of the soft tissues of the coral polyps provides nutrients for new coral growth, contributing to the continuous development of coral reefs.
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.
