Explanation:

An ecosystem consists of all the living organisms (biotic components) in an area interacting with the non - living (abiotic) components of their environment.

• Option A: A group of the same species that live in the same place at the same time is a population, not an ecosystem.
• Option B: A group of all abiotic components found in an environment is just part of an ecosystem (the non - living part).
• Option C: A group of organisms that can mate and produce fertile offspring, and that live in the same area is a species (in terms of biological species concept) or a population.
• Option D: A group of all the organisms living together in an area along with the abiotic components of their environment is the correct definition of an ecosystem.

Answer:

D. A group of all the organisms living together in an area along with the abiotic components of their environment.
