biota

This term functions as a collective noun encompassing all living organisms within a specific geographic area or time frame. It is primarily used in scientific, ecological, and paleontological contexts to describe the biological makeup of an environment without focusing on individual species.

Grammatically, biota is treated as an uncountable mass noun. It does not have a plural form because it already represents a totality of life; therefore, it cannot be counted as multiple biotas in standard scientific usage.
