Question

what is the limiting factor responsible for the low productivity of the open ocean in the saltwater biome?

Answer 1

Open oceans have relatively low primary productivity because of low levels of the essential nutrients nitrogen and phosphorus.

How much primary production relies upon various ecological factors. These factors incorporate the accessibility of fundamental inorganic supplements, especially nitrogen and phosphorus; water temperature; and the turbidity of the water. Open oceans have moderately low primary productivity on account of low levels of the fundamental supplements nitrogen and phosphorus.

As a result of the thickness distinction between surface water and the remote ocean across a large portion of the ocean, ocean dissemination can gradually once again introduce broke down supplements to the euphotic zone. By driving supplements out of the sunlit, light surface waters, ocean productivity really limits itself.
