Which consequence results when upwelling subsidence increases rapidly?

💡 Explanation

Nutrients decline when subsidence increases because rapid downward water movement disrupts the normal upwelling cycle. This inhibits nutrient delivery from depths via advection, therefore nutrient concentration reduces in upper layers rather than causing blooms.
