D.The flora and fauna of a geographical area.
B.That part of the Earth which is inhabited by living organisms
A.A community of organisms interacting with one another
C.A community of organisms together with the environment in which they live.
Correct Answer: Option C
An ecosystem is best described as a community of living organisms (biotic components) interacting with each other and with the non-living components (abiotic components) of their environment, such as air, water, minerals, and sunlight.
Option A only mentions the interaction between organisms and neglects the crucial role of the physical environment.
Hence, option C is the most accurate and complete description.
