Which outcome on a coral atoll is accelerated when burrowing shrimp populations increase?

💡 Explanation

Increased shrimp populations enhance bioturbation, turning over sediment layers, and homogenizing grain size rather than maintaining variations, because the shrimps' burrowing homogenizes the seabed structure; therefore, grain-size homogenization increases, rather than other effects that rely on diverse sediment layers.
