Which ecological outcome results when coastal upwelling is disrupted by increased surface water temperatures?

💡 Explanation

When upwelling is reduced due to increased surface temperatures, nutrient transport to photic zones decreases because thermal stratification prevents mixing, limiting phytoplankton growth. Therefore, coastal primary productivity declines, rather than other outcomes which need different environmental and nutrient conditions.
