Which outcome occurs when deep soil bioturbation decreases?

💡 Explanation

Reduced bioturbation slows the physical cycling of nutrients, because fewer organisms move materials, decreasing vertical nutrient flow. Therefore, the translocation rate lowers, rather than increased weathering or unrelated methane changes which depend on different mechanisms.
