Final answer:
A community is indeed composed of different populations of animals and plants, as it contains multiple populations of various species that coexist and interact within a common environment.
Step-by-step explanation:
True, a community is composed of different populations of animals and plants. In biological terms, a population refers to a group of organisms of the same species that live in the same area. Communities are essentially collections of multiple populations of various species that inhabit a shared environment and interact with one another. Communities are characterized by patterns of interactions among the organisms such as symbiosis, predation, and competition. The diversity of these populations in a community is a significant factor in ecology, as it helps to determine the health and functionality of the ecosystem they inhabit.
