Question
Which will most likely result if there is increased upwelling in a coastal area? A. more aquatic life B. less nutrients in the water C. higher water temperatures D. fewer nitrates
Solution
The answer is A. more aquatic life.
Here's why:
-
Upwelling is a process in which deep, cold water rises toward the surface. This typically occurs along coastlines.
-
This deep, cold water is often rich in nutrients. These nutrients include things like nitrates and phosphates, which are essential for plant growth.
-
When these nutrients reach the surface, they promote the growth of phytoplankton (microscopic plants that float in the water column).
-
Phytoplankton are the base of the marine food web. They are eaten by small animals, which are then eaten by larger animals, and so on.
-
Therefore, when there is increased upwelling, there is typically an increase in the amount of aquatic life in that area. This is because there are more nutrients available for the phytoplankton to grow, which in turn supports more life at all levels of the food web.
