How would you describe the characteristics and boundaries of the ecosystem in which you live? In what respects is your ecosystem an open one?

I'm going to assume this was a homework assignment.

First off, we don't know where you are from, so even if we DID describe our ecosystems, it wouldn't necessarilly help you, as ecosystems could change in mere miles.
Second, if we DID know where you are, no one here is going to do your homework for you. We can and will help you if you need help, but just posting a homework assignment like the one above doesn't let us effectively help you.

Please specify what you need help with if you would like help on this assignment.
