Question

Choose the correct statements:
1. Population is a group of organisms belonging to a species living in a particular area.
2. Populations of different species in a given habitat, interacting with one another constitute a community.
3. Population is a group of organisms belonging to different species.

• A. I & III only
• B. I & II only
• C. II & III only

Hint:

Population = one species in an area; Community = many species interacting in a habitat.

Answer 1

The Correct Option is B

- Statement I is correct: A population is defined as a group of individuals of the same species living in a specific geographic area at the same time.
- Statement II is correct: A community refers to populations of different species living together in a habitat and interacting with one another.
- Statement III is incorrect: It wrongly defines a population as consisting of different species, which is the definition of a community, not a population.

Answer 2

The term population refers to a group of organisms of the same species living together in a specific geographical area at a particular time. This means that all individuals within a population share similar genetic characteristics and can interbreed.

Statement 1 correctly defines a population as organisms belonging to a single species in a given area.

A community is formed when populations of different species live and interact within the same habitat. These interactions can include competition, predation, mutualism, and more, which influence the structure and dynamics of the community.

Therefore, statement 2 is also correct as it describes a community as multiple populations of different species interacting.

Statement 3, however, is incorrect because a population never consists of different species; that defines a community.

Hence, the correct statements are 1 and 2 only.
