Which outcome results when intense, long-term bioturbation affects a soil profile with volcanic horizons?

💡 Explanation

Intense bioturbation disrupts the distinct volcanic horizons because its mixing by organisms causes enhanced nutrient translocation and homogenization of soil properties therefore option A rather than distinct textural/chemical layers or soil cementation formations will occur.
