Its niche....but that's circular....but I'm somewhat baffled as to why you didn't use the term "niche"....AnyWay...."function" is a group selectionist term that indicates the person asking the question hasnt the foggiest notion about evolution.

The biotic factors of an ecosystem are the living factors - anything that lives within the ecosystem. The actual factors vary.
An Ecosystem is an environment or a culture within which the conditions or resources necessary for sustaining a number of organisms or species exist, which in turn, constitute and sustain the ecosystem in and of itsself.
