Correct option is B
Sol.
Forest Type A: Very large forest floor litter pool (5000 gC/m²) with low litterfall (50 gC/m²/yr) is characteristic of temperate coniferous forests, where needle litter decomposes slowly and accumulates.
Forest Type B: Moderate litter pool (1500 gC/m²) and moderate litterfall (300 gC/m²/yr) correspond to temperate deciduous forests with seasonal leaf drop and intermediate decomposition rates.
Forest Type C: Small litter pool (600 gC/m²) but high litterfall (600 gC/m²/yr) is typical of tropical forests, where rapid decomposition prevents litter accumulation despite high input.
Thus, option 2 correctly identifies the forest types.
Information Booster:
Temperate coniferous forests have slow decomposition due to acidic needles and cooler climate, resulting in large litter pools but low annual litterfall.
Temperate deciduous forests show seasonal patterns with intermediate litter pools and litterfall rates.
Tropical forests have high productivity and litterfall, but rapid decomposition limits litter accumulation.
