Which long-term outcome results from consistent bioturbation activity?

💡 Explanation

Consistent bioturbation causes increased homogeneity because animal movement mixes soil layers over time. This mixing disrupts layering by physical action, therefore reduces horizon contrast rather than maintaining stratification, where nutrients remain separated by depth.
