The correct answer is soil pH — Conclude that soil pH is the correct answer.
Step-by-step solution
- Identify components that are non-living: soil pH, water temperature, and light intensity are abiotic, whereas trees, insects, and fungi are biotic.
- Compare each option: (a) canopy-forming tree species – biotic; (b) soil pH – abiotic; (c) leaf litter – biotic; (d) insect pollinator – biotic.
- Select the option that represents a non-living factor, which is (b) soil pH.
- Conclude that soil pH is the correct answer.
Common mistake: Confusing soil characteristics with living organisms.
Concept tested: Abiotic versus biotic components
