Answer:
number of organisms
Explanation:
The biome can be defined as a set of plant and animal life, constituted by the grouping of contiguous types of vegetation and which can be identified at regional level, with similar conditions of geology and climate and which, historically, have suffered the same formation processes of the landscape, resulting in a diversity of its own flora and fauna.
The number of living organisms is not a factor that characterizes the biome, however precipitation, latitude and temperature are important for the characterization.
