The map shows areas of upwelling climate scientist predict that upwelling may intensify along the western coast of the united states. what would more intense upwelling mean for the area? a. more abundant marine species b. less productive seawater c. less photosynthesis d. more starved marine species

The answer is A. More abundant marine species

Upwelling will cause the movement of nutrient-rich water to the ocean surface. This will makes the water to have more nutrient, so there will be more photosynthesis happens. Photosynthesis will produce more food, so the amount of marine species that could survive would be higher.
