← GeographyWhich consequence results when increased bioturbation affects clay soils?
A)Nutrient leaching rate decreases slowly
B)Macropore formation and aeration increases✓
C)Capillary rise of water intensifies
D)Anaerobic conditions in the soil worsen
💡 Explanation
When bioturbation occurs, burrowing organisms increase soil macropores, therefore aeration and drainage rises, because animals create new channels. Soil structure loosens with mixing, rather than restricting flow as A suggests.
