which statement best describes an ecosystem? a group of the same species living together all living and nonliving things interacting in an area only the biotic factors in a region a large region with similar climate and organisms

Explanation:

An ecosystem is defined as a community of living organisms (biotic factors) interacting with the non - living components (abiotic factors) of their environment.

• Option 1: A group of the same species living together is a population, not an ecosystem.
• Option 2: All living (biotic) and non - living (abiotic) things interacting in an area fits the definition of an ecosystem.
• Option 3: Only considering biotic factors is incorrect as ecosystems also include abiotic factors.
• Option 4: A large region with similar climate and organisms is a biome, not an ecosystem.

Answer:

B. All living and nonliving things interacting in an area
