Which ecological consequence results when increased glacial meltwater impedes upwelling?

💡 Explanation

Reduced upwelling limits nutrient transport to surface waters, due to density stratification. This impedes the nutrient supply for phytoplankton because deep, nutrient-rich water is less accessible, therefore phytoplankton populations decline, rather than alternative effects linked to shifting temperature or oxygen.
