Carbon is essential for the survival, growth and reproduction of living things. It is a finite resource that comes in different forms and transfers from living to non-living things in various ways. Carbon stays balanced with other chemical reactions in the air and bodies of water through the carbon cycle.
A: The carbon cycle is important because all living things are made of carbon in one way or another. The carbon cycle is how carbon is exchanged throughout the earth: between the atmosphere, oceans, ecosystem and geosphere. If the carbon cycle fails, then life begins to break down, causing life to end.
