Answer 1

The permanent zone of upwelling occurs off the west coast of South America where the upwelling creates a productive fishery.

Step-by-step explanation:

The permanent zone of upwelling occurs off the west coast of South America where the prevailing winds blow along the surface waters near the coastline. Upwelling brings nutrient-rich deep ocean waters to the surface, creating a productive fishery. The upwelled nutrients support the growth of phytoplankton, which then becomes food for fish and other organisms in the food chain.
