Population

Definition

Population in microbiology refers to a group of individuals of the same species living in a specific habitat. These populations interact with their environment and other organisms within the ecosystem.

5 Must Know Facts For Your Next Test

1. Prokaryotic populations can vary greatly in size depending on environmental conditions and resource availability.
2. Populations of prokaryotes are often studied to understand community structure and dynamics within microbiomes.
3. Gene transfer between individuals in a population can lead to rapid genetic changes and adaptation.
4. Environmental factors like temperature, pH, and nutrient availability directly influence prokaryotic population growth.
5. Populations play a crucial role in biogeochemical cycles by breaking down organic matter and recycling nutrients.
