Which outcome contributes the most when earthworm populations flourish and soil is compacted by grazing animals?

💡 Explanation

Enhanced nutrients dispersion happens because the soil experiences increased bioturbation as worms redistribute organic matter and relieve compaction; therefore topsoil nutrients become readily available to plants, rather than remaining stratified in layers.
