Which outcome occurs when increased bioturbation affects floodplain soil?

💡 Explanation

Bioturbation disrupts soil structure via physical mixing. This mechanism causes decreased aggregate stability because burrowing organisms decrease soil cohesion by disrupting particle arrangements; therefore, the soil is more prone to erosion rather than horizon development under optimal conditions.
