Multiple Choice

Two students give the following presentation to their classmates:

Student 1 starts the presentation by describing members of one species.

Student 2 adds information about members of another species and explains that members of both species interact with each other AND with the abiotic factors in their environment.

Which statement BEST explains why Student 1 is describing a Population and Student 2 is describing an Ecosystem.

• Ecosystems consist of all organisms living and interacting in a given area & individuals are organisms.

• An organism is a species, & many species living in the same area make up a population.

• A population consists of a group of the same species, & ecosystems are communities interacting with abiotic factors

• Communities consist of organisms, & organisms interacting with living and non-living factors in the environment make up a population.
