Carbon is the most important element for living organisms on Earth; all life here is carbon based.  Carbon travels through an endless cycle as it is used by living things, is recycled as carbon dioxide and then reintroduced back to living organisms.  Carbon is exchanged through many different processes and today you will learn about some of them.
