What are bats niche? :o?

You mean what is a bat's niche? If that's what you mean then let me start by explaining what a niche is. A niche is a term describing the relational position of a species or population in its ecosystem.Where it lives and eats, and what eats it. How it interacts with all biotic and abiotic factors etc. Therefore a bats niche would be the place it lives(e.g. a cave) what it eats(e.g insects) how it eats (e.g. It hunt's the insect down while flying, and keeps track of it by using a "feeding buz" and it eats it) and all that other stuff
