This particular current brings nutrient rich cold water up to the surface of the ocean which drives photosynthesis of phytoplankton and forms the base of the ocean food web What is it called? Downwelling Deep Ocean Current Global Conveyor Belt Upwelling

The correct answer is:<br /><br />**Upwelling**<br /><br />### Explanation:<br />Upwelling is the process by which deep, cold, and nutrient-rich water rises to the surface of the ocean. This phenomenon occurs when surface waters are displaced by wind or other forces, allowing deeper water to replace it. The nutrients brought to the surface fuel the growth of phytoplankton, which are microscopic plants that perform photosynthesis. Phytoplankton form the base of the ocean food web, supporting a wide variety of marine life, including fish, seabirds, and larger predators.
