← GeographyWhich outcome relating to soil structure results more rapidly when riparian earthworm populations experience a trophic cascade?
A)Homogenization increases through effective bioturbation.✓
B)Leaching increases with reduced compaction.
C)Salinization increases via capillary action.
D)Weathering decreases from limited moisture.
💡 Explanation
Increased earthworm abundance quickens soil homogenization because higher earthworm density leads to enhanced bioturbation, mixing soil layers effectively; therefore, soil structure changes more promptly than alternative processes affecting soil structure and not driven by cascading trophic effects.
