Concept:A population is a group of organisms of the same species, while a community consists of multiple interacting populations of different species.
Explanation:In ecology, a population represents all the members of a single species living together in one area at the same time, such as all tilapia fish in a pond.
A community, however, is made up of all the different populations that coexist and interact in a particular habitat, such as fish, insects, frogs, and algae in the same pond.
Therefore, the key difference is the level of organisation: organisms in a population belong to one species, whereas organisms in a community belong to many different species.
This means that a community is composed of various populations, and each population is composed of the same species.
Answer:B. a community is made up of populations of living organisms while a population is made up of organisms of the same species
