Mini Project #2

The Carbon Cycle

Mini project #2- Complete the missing links in the carbon cycle

Carbon Cycle- The main function of the carbon cycle is to convert carbon dioxide into living matter and then back. The carbon cycle moves, in its many forms, between the biosphere, atmosphere, oceans and geosphere. The carbon cycle is known to be a great natural recycler of carbon atoms which many factors on earth rely on, which makes it very important to keep the carbon cycle flowing and balanced. 

A simple explanation of how the carbon cycle works mainly deals with the earths plants and animals. First of all the plants absorb carbon dioxide from the atmosphere and use it, combined with water from the soil and make substances necessary for growth. The process of photosynthesis is involved in changing the carbon atoms from carbons to sugars. Animals eat plants and use the carbon dioxide contained to build their own tissues. Animals return the carbon dioxide into the atmosphere when they breathe and also when they die and the decomposition remains in the soil. The carbons left in the soil are used for a new plants growth.
