Which one of the following does not belong to the biotic community?
- (a)Water
- (b)Human
- (c)Protozoa
- (d)Bush
Correct — A, Water. A biotic community is the assemblage of living organisms in an area, so its members must be alive. A human, a protozoan and a bush are all living, but water is a non-living physical substance, making it an abiotic factor rather than a member of the biotic community.
- (b)Human — A human is a living organism, so it is a member of the biotic community — it does belong, so it is not the odd one out the question asks for.
- (c)Protozoa — Protozoa are living single-celled organisms, so they are part of the biotic community and do belong to it, not the exception.
- (d)Bush — A bush is a living plant, so it belongs to the biotic community and is not the item that fails to belong.
