← GeographyWhich feedback loop is enhanced when excessive burrowing organisms decrease soil stability?
A)Increased rate of soil erosion✓
B)Enhanced mineral nutrient availability
C)Reduced vegetation success locally
D)Increased groundwater infiltration rate
💡 Explanation
Increased animal activity reduces the soil's cohesive strength via bioturbation. This accelerates soil erosion because surface particles detach more easily and are moved away rapidly. Thus, enhanced erosion occurs rather than enhanced nutrients or other factors; these depend upon other separate mechanisms.
