Which outcome directly increases when bioturbation intensifies in topsoil?

💡 Explanation

Enhanced nutrient availability results because bioturbation increases soil porosity, which improves aeration and water infiltration, and accelerates decomposition from increased access for soil organisms; therefore nutrients cycle faster rather than remaining locked in organic matter.
