What is Population? Meaning and Definition

A population refers to a group of organisms of the same species that live in a specific geographic area and have the ability to interbreed.

Definition of Population:

In biology, a population is a collection of individuals of the same species living in a particular area at a given time. These organisms interact with each other and share resources such as food, water, and shelter.

Key Features of a Population:

1. Same Species: All individuals belong to the same species.

2. Same Location: They exist in a specific geographical area.

3. Interbreeding: They can reproduce among themselves.

4. Size and Density: The number of individuals and how they are distributed in the area.

5. Growth and Changes: Populations increase or decrease due to births, deaths, immigration, and emigration.
