Detailed explanation-1: -So, the correct answer is ‘Open oceans’.
Detailed explanation-2: -So, the correct answer is ‘Open oceans’.
Detailed explanation-3: -Answer and Explanation: The open ocean has the least primary production in aquatic biomes. Open ocean’s surface water is deficient in nutrients as the dead organic matter sink into the ocean.
Detailed explanation-4: -So most of the ocean surface is not very productive. The water is too deep for storms to stir up nutrients from the bottom and there isn’t upwelling. The average ocean productivity is about 50 grams carbon per square meter per year.
Detailed explanation-5: -Because of the density difference between surface water and the deep sea across most of the ocean, ocean circulation can only very slowly reintroduce dissolved nutrients to the euphotic zone. By driving nutrients out of the sunlit, buoyant surface waters, ocean productivity effectively limits itself.
