Water is a universal solvent
Upwelling is important to mix the nutrients that are present deep inside the water.Updewelling is a phenomenon in which the deeper water rises and gets mixed to the surface water to promote the growth of phytoplanktons and seaweeds as the water that is present deep inside is rich in nutrients.These phytoplanktons serve as as source of energy for large fishes and other aquatic animals. As these large animals are higher in population and are an important part of food chain and they also provide food to different marine mammals ,sea birds.The deep water infuses with costal water so to serve as a fuel for high productivity of marine ecosystem.

The other set produces hormones growth regulating, stress releasing and stimulating and inhibiting hormones are dopamine, corticotrophin-releasing hormone, growth hormone-releasing hormone, gonadotropin-releasing hormone, somatostatin, and thyrotropin-releasing hormone.
