Which term describes the variety of life across a region, including species diversity and genetic variation?

Explanation:
This question is about the term for the variety of life across a region, including the number of species, how they are represented, and the genetic variation within them. That broad concept is biodiversity, which covers species diversity, genetic diversity, and ecosystem diversity in a given area. The other terms refer to narrower ideas: population means the individuals of a single species in an area; a community is all the populations of different species living together and interacting in that area; a niche is the specific role a species plays in its environment. So biodiversity best fits the description.
