what is the difference betwen an ecosystem, ecosphere and biosphere? What are they exactly? and in order of how 'large' they r which one would be the 'largest'? if u get my drift. my biology teacher has not explained it very well. Can u help me?

Interesting question [] I'm not too sure either, to be honest [].
I think biosphere includes everything. An ecosystem consists of a community and its physical environment. The rest I'm not sure.
Anyone know ecology?

Meanie! I like that in a person!  []

First post in that thread should be: Google and Wikipedia are your friends!

Why bother when some kind person will put it into words which you can transfer straight onto your exercise book page and impress the teacher?
