When coral animals die their skeletons remain. More corals build on top of them, gradually forming a coral reef
When coral animals die their skeletons do indeed fall to the sea floor. This is the only place where they can go.
Yes. Organisms die and their skeletons collect to make coral.
Coral reefs form as coral polyps secrete calcium carbonate to create hard skeletons that build up over time. These skeletons create the structure and foundation for the reef, which then grows as more coral polyps settle and reproduce on top of existing skeletons. Over time, this process creates the diverse and intricate ecosystems we know as coral reefs.
basic answer, they suck up calcium and other elements from the water to build their skeletons. when they die, another coral builds upon the dead skeletons.
Coral polyps are tiny animals that build protective calcium carbonate skeletons around themselves. Coral polyps create the basic structure of coral reefs with the help of single-celled algae.
Shale rock is indirectly formed of skeletons and ancient coral animals. Clay minerals and tiny fragments of minerals like quartz and calcite make up shale. Calcite comes from the reaction of CaCO3, or calcium carbonate with Hydrogen ions. CaCO3 is a component of shells and bones.
called hermatypic coral.
Coral reefs are made up of coral, the shell-like structures that the tiny sea animals build as their "houses". Each year, a living coral reef builds a new layer of coral; you might think of it as the collected skeletons of all the previous inhabitants of the reef. (Except that for coral, their "bones" are on the outside.)
Coral animals, known as polyps, extract calcium carbonate from ocean water and use it to build their hard exoskeletons. These exoskeletons form the structure of coral reefs as multiple polyps work together to create a complex network of interconnected skeletons. Over time, the accumulation of these skeletons contributes to the growth and formation of coral reefs.
