Winds that cause ocean currents can be affected by the coriolis effect, resulting in upwelling currents. how would an upwelling current increase the abundance of aquatic organisms?
upwelling brings cold, nutrient-poor water to the surface, which would decrease the abundance of aquatic organisms.
upwelling brings cold, nutrient-rich water to the surface, which allows for an increase in aquatic organisms.
upwelling brings warm, nutrient-poor water to the surface, which allows for an increase in aquatic organisms.
upwelling brings warm, nutrient-rich water to the surface, which would decrease the abundance of aquatic organisms.

Upwelling brings cold, nutrient-rich water to the surface, which allows for an increase in aquatic organisms.

Explanation:

Upwelling currents occur in the neritic zone of marine ecosystem. Upwelling currents bring nutrient rich, cold water to the surface of neritic zone as a result of which warm and nutrient deprived water on the surface of neritic zone is displaced. This cold and nutrient rich water which reaches this zone further leads to the increase in the population of aquatic organisms.
