Question

which phrase describes a population?
a group of different communities in an area
organisms of the same species living in an area
nonliving things that interact with living things in a region
organisms that belong to the same community within a region

Explanation:

A population is defined as a group of organisms of the same species living in a specific area. Let's analyze each option:

• "a group of different communities in an area" is incorrect. Different communities make up an ecosystem, not a population.
• "organisms of the same species living in an area" aligns with the definition of a population.
• "nonliving things that interact with living things in a region" describes the abiotic components of an ecosystem, not a population.
• "organisms that belong to the same community within a region" is wrong. A community consists of multiple populations.

Answer:

organisms of the same species living in an area
