In an estuary a zooplankton consumes a phytoplankton with a small globule of PCBs attached to it. A fish consumes the zooplankton as well as many other zooplankton. A larger fish consumes the small fish and then a gull consumes the larger fish. The increased concentration of the chemical at the top of the food chain is an example of biomagnification. bioaccumulation. synergistic properties. PCB persistence. synergistic interactions.

How does upwelling affect coastal fisheries? upwelling damages nutrient supplies at coastal fisheries as the warm, nutrient-rich surface water is replaced by nutrient-poor, cold water. upwelling damages nutrient supplies at coastal fisheries as the cold, nutrient-rich surface water is replaced by nutrient-poor, warm water. upwelling improves the nutrient supply at coastal fisheries as the warm, nutrient-rich surface water replaces the nutrient-poor, cold water. upwelling improves the nutrient supply at coastal fisheries as cold, nutrient-rich water replaces the warm, nutrient-poor surface water.
