Which term describes all the different populations living in a given area?

• A. Community
• B. Climatic factors
• C. Contest competition
• D. Biosphere

Answer: (A)

The term describes all the different populations living in a given area is community. A population is all individuals of one species in that area, so when you combine populations of all species—plants, animals, microbes—you get the community. For example, in a meadow the populations of grasses, flowers, beetles, birds, and earthworms all share the same space and interact in various ways. Together they form the meadow’s community. Climatic factors are the non-living conditions that influence life, like temperature and rainfall. The biosphere is the global sum of all ecosystems on Earth. Competition refers to how organisms fight for resources, not a label for all populations in an area.
