The answer to this question is an animal that lies in the phylum cnidaria: coral polyps.
oysters
Precipitation from solution, and skeletons of marine animals.
a ridge is a calcium carbonate big mound consisting water breathing plants and animals.
A water ecosystem formed from the calcium carbonate shells secreted by a particular animal is known as a coral reef. These entail tiny marine animals and are considered to be a tourism attraction.
Calcium Carbonate <3
The bulk of marine skeletal remains are composed of the mineral calcite. Some marine organisms also have shells of aragonite or silica.
mineral calcite (calcium carbonate) usually found in marine organisms.
Calcium carbonate is a major component of sedimentary rocks such as limestone, chalk, and marble. These rocks form from the accumulation of marine organisms' shells, coral reefs, and precipitated calcite minerals.
The carbonate sands would indicate that they are the weathered and eroded remains of the skeletons of small marine animals (like corals) whose exoskeleton is composed of these minerals.
A calcisponge is any of a group of marine sponges containing calcareous spicules - spicules which resemble calcium carbonate.
The marine biologists do not recognize that a critical component to calcium carbonate shellfish exoskeleton production is dissolved carbon dioxide gas because the component has no scientific or chemical representation.
Jacques-Yves Cousteau recognized that coral reef exoskeletons were composed of calcium carbonate dissolved CO2 production, thanks to his research in the underwater world, field not covered by marine biologists.
Corals are marine organisms from the class Anthozoa and exist as small sea anemone-like polyps, typically in colonies of many identical individuals. The group includes the important reef builders that are found in tropical oceans, which secrete calcium carbonate to form a hard skeleton
