- Faster humus loss
- Greater leaching
- Organic build up
- Faster breakdown
Show answer and solution
Correct answer: C. Organic build up
Inhibited decomposition lets organic matter accumulate.

Worked practice questions
Plants capture what share of the photosynthetically active radiation?
- 50-60 per cent
- 2-10 per cent
- 90-100 per cent
- 20-30 per cent
Show answer and solution
Correct answer: B. 2-10 per cent
Only 2-10 per cent of PAR is captured, yet it sustains the living world.
The producers in an aquatic ecosystem include
- Zooplankton
- Molluscs
- Phytoplankton
- Decomposers
Show answer and solution
Correct answer: C. Phytoplankton
Phytoplankton, algae and higher plants photosynthesise and so are producers.
