Which outcome occurs when earthworm populations facilitate bioturbation in topsoil?

💡 Explanation

Bioturbation by earthworms mixes soil, benefiting aggregate formation because their burrowing creates stable pore structures enhancing soil structure; therefore, aggregation happens, rather than increased erosion (選項Ａ ), altered nutrient levels(С), or inhibited sequestration (D).
