Which outcome occurs when earthworm populations decline drastically?

💡 Explanation

Reduced soil horizon mixing will occur because declining earthworm populations decrease bioturbation, disrupting soil structure and compositions; therefore horizon blending decreases rather than fertilization being increased by the fauna's absence.
