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.
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 skeletons are extremely diverse, so it is impossible to answer this in general.
Coral skeletons are composed of calcium carbonate, which is easily broken down in the stomach, and absorbed, and then used by the body to build bones.
