Which feedback effect accelerates soil horizon mixing during intensive bioturbation?

💡 Explanation

Enhanced decomposition exposes buried minerals to weathering, thereby accelerating bioturbation because increased nutrient availability stimulates increased burrowing, which further mixes soil. Therefore, decomposition enhances the process, rather than slowing down biotic activity, as occurs with reduced burrowing.
