Carbon can bind to, and to other carbon molecules, four other groups around it. Hence, it is called a “carbon sink.” Marine animals convert carbon to calcium carbonate and this forms the raw building materials require to create hard shells, similar to the ones found in clams and oysters. Also, since nearly all molecules in the body contain carbon, carbon is so essential to life. When organisms with calcium carbonate shells die, their body decomposes, leaving behind their hard shells.
