Which changes due to increased stratification limit upwelling?

💡 Explanation

Increased stratification reduces vertical water movement because it enhances the barrier to the upwelling mechanism; reduced movement diminishes nutrient replenishment to the surface, therefore limiting primary production rather than enhancing mixing or changing salinity.
