Calcifying algae

Calcifying algae are types of algae that absorb calcium from their environment and use it to create a hard, calcified structure. These organisms are important in marine ecosystems, as they contribute to coral reef formation and provide habitat for various marine species. By building calcium carbonate skeletons, calcifying algae help stabilize the ocean floor and influence the underwater landscape. They are also sensitive to changes in water temperature and acidity, making them indicators of environmental health in oceans and coastal areas. Their decline can have significant impacts on marine biodiversity and ecosystem function.
