Question

How do upwelling currents near the shore affect the abundance of aquatic organisms along the shoreline?

Answer 1

They bring the nutrients toward the shore and increasing the abundance of the organisms.

Explanation:

The deep water brought out to the surface of the land is often rich in the nutrients, coastal up-welling supports the growth of the seaweed and the plankton.

The nutrients are used as the food for the marine animals, birds, fish. The up welling method generates some of the world's most fertile ecosystems. The up welling is the process which helps to move the deeper water, which is rich in the nutrients to warmer the shallower water in the ground.
