Which ocean ecosystem effect occurs when upwelling weakens notably?

💡 Explanation

Weakened upwelling diminishes nutrient supply to surface waters; phytoplankton growth decreases due to nutrient limitation by Liebig's Law. Thus, blooms shrink and carbon supply decreases, because nutrient delivery diminishes, therefore reduced productivity occurs rather than alternate ocean events.
