Which consequence results when nutrient supply limits plankton growth within an ocean gyre?

💡 Explanation

Reduced plankton growth decreases carbon intake via photosynthesis which influences regional carbon sequestration; this occurs because the biological pump mechanism relies on surface productivity. Gyres usually trap nutrients; therefore, the overall carbon sequestration is reduced, rather than upwelling increasing or deep water formation.
