A group of organism of different species living in a particular area is described as a

1. Analyze the question The question asks for the term describing a group of organisms of different species living together in a particular area. The key phrases are "different species" and "particular area."

2. Explain the concept These ecological terms form a hierarchy:

• Population: individuals of the same species living in an area (e.g., all the tilapia in a pond).
• Community: all the different species (plants, animals, microbes) living and interacting in an area (e.g., all the fish, frogs, insects and plants in the pond).
• Ecosystem: the community plus its non-living (abiotic) environment.
• Colony: a group of the same species living closely together, often attached or cooperating (e.g., ants, termites, bacteria).
• Niche: the role or functional position of an organism in its habitat (what it eats, where it lives, how it interacts), not a group of organisms.

3. Step-by-step solution

• Option A, colony: same species, so it does not fit.
• Option B, community: multiple species in one area, so it fits.
• Option C, population: same species only, so it does not fit.
• Option D, niche: a role, not a group, so it does not fit.

4. Answer The correct answer is B. community.

5. Exam tip Remember: Population = Pne species (same species only), Community = Combination of different species. If the question says "different species" or "all the living things" in an area, think community. If it says "same species," think population.
