Which feedback increases floodplain sediment nutrient heterogeneity due to seasonal shifts?

💡 Explanation

Increased seasonal flooding enhances *bioturbation* by mobilizing buried organic matter because aquatic organisms cycle surface and subsurface sediments following flooding, therefore resulting in nutrient variability, rather than stabilized conditions, within the floodplain.
