Which term describes all the different populations that live together in an area?

• A. Biome
• B. Mimicry
• C. Parasitism
• D. Community

Answer: (D)

In ecology, understand the different levels of organization: a population is all individuals of one species in an area, while a community is all the populations of different species living together and interacting in that same place. Saying “all the different populations living together here” points to the community, because it includes fish, plants, insects, fungi, and more all coexisting and interacting in that spot. A biome is a larger geographic region defined by climate and major life forms, not just the living things in one small area. Mimicry is a survival strategy, and parasitism is a type of interaction between species. So the term that describes all the different populations that live together in an area is community.
