Which feedback to nutrient upwelling results when benthic bioturbation decreases?

💡 Explanation

Decreased bioturbation reduces nutrient transport from sediments into the water column because it impairs the process of mixing, therefore primary productivity drops, rather than enhanced sediments reducing light penetration for photosynthesis in upper waters.
