Which outcome results from reduced bioturbation during soil pedogenesis?

💡 Explanation

Reduced bioturbation decreases organism mixing, so soil organic matter forms a distinct layer rather than mixing; therefore, organic matter accumulates on the surface, rather than distributing throughout the soil profile, because mechanical mixing diminishes.
