Explanation:
Detailed explanation-1: -Compared to land, the open oceans are nutrient-poor environments.
Detailed explanation-2: -In the ocean, as there is no shortage of water, the dominant factors impacting phytoplankton growth are sunlight and nutrients. Often in the open ocean, however, nutrients are at their highest concentrations deep below the sunlit surface layer of the ocean.
Detailed explanation-3: -Broadly important nutrients include nitrogen (N), phosphorus (P), iron (Fe), and silicon (Si). There appear to be relatively uniform requirements for N and P among phytoplankton.
