Why Are Upwellings Important To Ocean Ecosystems

Currents also are a major factor in ocean ecosystems. Two types of current motion upwelling and downwelling strongly influence the distribution and abundance of marine life. … When currents upwell or flow up to the surface from beneath they sweep vital nutrients back to where they''re needed most. How does coastal upwelling affect ecosystems?
