← GeographyWhich outcome inhibits phytoplankton blooms when increased stratification disrupts a gyre?
A)Nutrient upwelling reduction✓
B)Increased sunlight penetration
C)Enhanced CO2 absorption
D)Deceased grazing intensity
💡 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.
