Which increased shallow soil horizon mixing results, when bioturbation intensity increases?

💡 Explanation

Greater bioturbation results in decreased soil profile stratification because biological activity causes mixing of soil horizons, thereby minimizing distinct layering, rather than enhancing it; therefore, soil becomes less layered rather than more layered.
