Algae are phytoplankton capable of photosynthesis. How do ocean currents affect algae populations?

A) Ocean currents deposit nutrients at the ocean floor, where the algae are present.

B) Ocean currents push the algae to the ocean floor, where the nutrients are present.

C) Ocean currents move the cold, nutrient-rich water to the surface to provide renewed food source for algae.

D) Ocean current move algae from the poles toward the equator, where the amount of sunlight received is more.
