Iron is an essential element that cycles between the Earth's atmosphere, oceans, soils and living organisms. It dissolves in water and is used by many organisms, with some bacteria even able to dissolve iron from rocks. Iron cycles between its ferrous and ferric states as it interacts with oxygen and other elements like sulfur in the environment and living things.
