Generally, environment can be classified as following categories. Which among the following is NOT a part of such category?
- (a)Operational Environment
- (b)Physical Environment
- (c)Cultural Environment
- (d)Biological Environment
Correct — A, Operational Environment. In environmental studies and geography the total environment is conventionally divided into three broad categories: the physical (abiotic) environment — land, water and air (lithosphere, hydrosphere, atmosphere); the biological (biotic) environment — plants, animals and micro-organisms, including humans; and the cultural / social environment — the human-made, socio-economic and technological surroundings. 'Operational environment' is a term from management and systems studies, not one of these standard environmental categories, so it is the odd one out and the correct answer to this 'NOT a part' question.
- (b)Physical Environment — A genuine category — the abiotic surroundings of land, water and air (lithosphere, hydrosphere, atmosphere). It IS part of the classification, so it is not the exception being sought.
- (c)Cultural Environment — A genuine category — the human-made, social, economic and technological environment created by people. It IS part of the classification, so it is not the exception.
- (d)Biological Environment — A genuine category — the biotic world of plants, animals and micro-organisms. It IS part of the classification, so it is not the exception.
The environment is the sum total of surroundings that influence an organism. For study it is classified into three interacting components: physical/abiotic (non-living matter and energy), biological/biotic (all living things) and cultural/social (the human-created world of economy, institutions and technology). Together they form the human ecological system.
This is a 'NOT a part' question, so eliminate the three real categories and pick the intruder. Physical, Biological and Cultural are the textbook trio; 'Operational' belongs to organisational/management jargon (the operating environment of a firm), not to the geography of the environment — that mismatch flags it as the answer.
- Environment is broadly classified into Physical (abiotic), Biological (biotic) and Cultural (social / man-made) components
- Physical / abiotic: lithosphere (land), hydrosphere (water), atmosphere (air)
- Biological / biotic: flora, fauna, micro-organisms and human beings
- Cultural / social: economy, institutions, technology and the built environment created by humans
Physical, Biological and Cultural are the three genuine categories; 'Operational' is the intruder, so option (a) is the answer.
- Being drawn to 'Operational' because it sounds technical — it is not an environmental category
- Assuming only 'natural' components count and wrongly rejecting the cultural/social environment
UPPSC and UPSC frame conceptual definition questions as 'which is NOT' odd-one-out items — know the physical/biological/cultural trio and spot the term borrowed from another discipline.

The biotic component of the environment includes which of the following?
- (a)Plants, animals and micro-organisms
- (b)Land, water and air
- (c)Roads, factories and cities
- (d)Temperature and sunlight
Answer(a) Plants, animals and micro-organisms — these living things form the biological/biotic environment; land/water/air are abiotic and built structures are cultural.
- practice — not a real PYQ
The lithosphere, hydrosphere and atmosphere together constitute which part of the environment?
- (a)Physical (abiotic) environment
- (b)Biological environment
- (c)Cultural environment
- (d)Operational environment
Answer(a) Physical (abiotic) environment — the non-living matter of land, water and air.
