Question

Which is a biotic component of an ecosystem?
A) water
B) archaea
C) rock
D) salinity
E) temperature

Accepted Answer

Biotic components of an ecosystem are living or once-living organisms. Archaea are microorganisms that are living organisms and thus a biotic component of an ecosystem. Water, rock, salinity, and temperature are all abiotic components since they are non-living physical or chemical factors in the environment.
