Which outcome results when reduced soil organisms conduct bioturbation?

A)Aggregated topsoil horizon formation slows
B)Rate of loess deposition increases
C)Chemical weathering intensity accelerates greatly
D)Erosion rates begin declining sharply

💡 Explanation

Reduced soil organism diversity decreases the rate of **bioturbation**, a mixing and aggregation mechanism, because soil biota rework textures. Therefore, aggregated topsoil forms slower rather than faster; high bioturbation accelerates loess mixing, not deposition.
