Question

Which of the following exactly belongs to the abiotic component of the environment?

• A. animals and water
• B. plants and soil
• C. water and soil
• D. microorganisms and water

Hint:

Abiotic = non-living; Biotic = living. Water and soil are purely abiotic.

Answer 1

The Correct Option is C

To determine which option belongs exactly to the abiotic component of the environment, we analyze the given choices based on the distinction between biotic and abiotic factors.

1. Understanding Biotic vs. Abiotic Components:
- Biotic: Living or once-living organisms (e.g., animals, plants, microorganisms).
- Abiotic: Non-living physical and chemical elements (e.g., water, soil, air, minerals).

2. Evaluating the Options:
- Option 1 (animals and water): Animals are biotic; water is abiotic → Mixed.
- Option 2 (plants and soil): Plants are biotic; soil is abiotic → Mixed.
- Option 3 (water and soil): Both water and soil are abiotic → Fully abiotic.
- Option 4 (microorganisms and water): Microorganisms are biotic; water is abiotic → Mixed.

3. Conclusion:
Only Option 3 (water and soil) consists entirely of abiotic components.

Final Answer:
The correct choice is \( \boxed{\text{water and soil}} \).
