Which mechanism causes increased anchovy populations following strong coastal upwelling events?

💡 Explanation

When strong upwelling occurs, nutrient-rich water from the deep ocean rises, enhancing phytoplankton growth because sunlight provides energy for photosynthesis boosting food supply supporting anchovy populations. Phytoplankton blooms from increased nutrients stimulates the food-web therefore, anchovy populations increase, rather than predation reduction, shorter incubation, or increased clarity requiring separate independent and distinct environmental conditions.
