Which soil profile alteration results from prolonged bioturbation?

💡 Explanation

Extensive burrowing and mixing by organisms causes blending because process disrupts distinct layers by redistributing materials in the profile—therefore, horizon boundaries become diffuse—rather than developing stratification.
