name some of the biogeochemical cycles and how do they affect our lives

Question

Since this is not my area of expertise, I searched Google under the key words "biogeochemical cycles" to get these possible sources:

http://www.enviroliteracy.org/subcategory.php/198.html

You can find information more quickly by using the appropriate key words to do your own searches.

I hope this helps. Thanks for asking.
