Why is the humus layer typically thicker in a cool, temperate, forest soil than in a tropical rainforest soil?
A)Less humus is produced in the tropical rainforest because the B horizon is so poorly developed.
B)Less humus is produced in the cool, temperate forest but the rate of decay and oxidation is slower than in a tropical rainforest.
C)More humus is produced in the tropical rainforest, but it is quickly washed away by the heavy rains.
D)In a tropical rainforest, the forest-floor litter is often burned during the dry season.

The cooler temperatures in a temperate forest slow down the rate of decay and oxidation of organic matter, allowing more time for the buildup of humus. In contrast, the warm and wet conditions in a tropical rainforest accelerate the decomposition process, resulting in less time for the accumulation of humus.
