Calcite: calcite forms and is stable at the Earth's surface. Some calcite is formed from precipitation, but much of the calcite in sedimentary rocks is formed by biological activity. Many marine organisms secrete skeletal material (shells) of calcite.In addition to these three most abundant minerals, some sedimentary rocks also contain the iron oxides hematite and limonite, and small amounts of feldspars and micas.any marine organisms secrete skeletal material (shells) of calcite.

Unlike kelp, coral is seen in warm waters. Coral reefs make up a large amount of the ocean's ecosystem. It's estimated that coral supports up to 25 percent of marine life. Coral is not just made up of aquatic plants, but it also has a rocky surface that allows tiny fish and eels to hide within the crevices.hytoplankton. Phytoplankton are some of the most primitive plants in the ocean. Although they are very tiny, these plants account for a majority of the oxygen that is produced for the air that humans breathe.
