What is the biosphere?

Answer 1

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

http://en.wikipedia.org/wiki/Biosphere

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
