Which outcome is caused by increased acidity inhibiting upwelling?

💡 Explanation

Reduced pH impairs calcium carbonate formation for shell-forming plankton; this in turn diminishes their density, impairing the *biological pump*, because less organic matter sinks, therefore nutrient upwelling decreases, rather than increases, and phytoplankton populations decline given less access to vital resources.
