Discuss the biological impact of upwelling and downwelling on marine ecosystems. Provide examples of marine systems that are impacted by these processes in your answer
What will be an ideal response?
Upwelling is the upward movement of cold, deep, nutrient-rich water to the surface; downwelling is the downward movement of surface water to deeper parts of the ocean. Upwelling hoists chilled water to the surface. This cold water, rich in nutrients, creates high productivity (an abundance of microscopic algae), which establishes the base of the food web and, in turn, supports incredible numbers of larger marine life like fish and whales. Downwelling, on the other hand, is associated with much lower amounts of surface productivity but carries necessary dissolved oxygen to those organisms living on the deep-sea floor.
