Which term describes the variety of life across all species in an ecosystem?

Explanation:
Variety of life across all species in an ecosystem is biodiversity. It covers the total variety of living things, including how many different species are present, the genetic variation within those species, and the range of ecosystems in the area. The description emphasizes all species together, which makes biodiversity the most complete term. Species richness simply counts species, genetic diversity looks only at variation within a species, and ecology is the study of how organisms interact with each other and their environment. So biodiversity best fits.
