Question

which of these is the most accurate description of a population?

a population is a group of individuals that belong to the same species and live in the same area.

a population is a single living thing that cannot breed with other living things.

a population is a group of different species all living in the same forest.

Explanation:

⚡ Using what you learned: hierarchical levels of biological organization

Step 1: Analyze the levels of organization

In ecology, life is organized into hierarchical levels:

• Organism: A single living individual.
• Population: A group of individuals belonging to the same species living in the same geographic area at the same time.
• Community: All the different populations of different species living and interacting in the same area.
• Ecosystem: The community of living organisms interacting with their non-living physical environment.

Step 2: Evaluate the options

• Option 1: "A population is a group of individuals that belong to the same species and live in the same area."

This matches the scientific definition of a population perfectly because it specifies both the same species and the same geographic location.

• Option 2: "A population is a single living thing that cannot breed with other living things."

This describes an individual organism, not a population.

• Option 3: "A population is a group of different species all living in the same forest."

This describes an ecological community, not a population.

Answer:

A population is a group of individuals that belong to the same species and live in the same area.
