When describing a community, a biologist would discuss

B. biome that exists in the biosphere.

C. every organism that can produce offspring together.

D. every ecosystem that is part of a biome.

I think the correct answer from the choices listed above is option A. When describing a community, a biologist would discuss every population that lives together in an area. For a biologist, a community is a group of living organisms that stays in a certain area. Hope this answers the question.
