Upwellings are vital in developing a food chain. The process starts off with the deep ocean. Deep water is more nutrient rich than surface water because the nutrients, plankton or “fertilizer” in the ocean sink to the bottom. Upwellings brings those lost nutrients that sunk to the bottom back up to the surface, which aids algae and plankton growth. Then this algae and zooplankton will become food for other animals.
