Biology - Biogeochemical Cycles
In this lesson we learn about the various nutrients like water, carbon, nitrogen and oxygen that are used in a cyclic fashion to maintain balance in the biosphere. The process by which gases maintain an average atmospheric temperature is called greenhouse effect. The ozone molecules form the ozone layer but are getting fast depleted by gases such as CFC's.
