Which outcome inhibits phytoplankton blooms when increased stratification disrupts a gyre?

💡 Explanation

Decreased stratification normally allows nutrient-rich upwelling, fueling blooms; inhibiting this upwelling reduces phytoplankton due to decreased nutrient availability. Because nutrient upwelling is suppressed by increased stratification, therefore phytoplankton suffer, rather than thrive with grazing reductions.
