Which outcome occurs when burrowing earthworms enhance soil?

💡 Explanation

Enhanced soil structure follows bioturbation because earthworm activity mixes organic matter and minerals via **pedogenesis**, therefore increasing aggregate stability, rather than leading to compaction or reduced productivity generally arising from nutrient leaching.
