Deserts, tundra, and the deep ocean are the least productive ecosystems, typically having an energy fixation of less than 0.5 × 103 kilocalories per square meter per year (thousands of kcal/m2/yr; it takes one calorie to raise the temperature of one gram of water by 34°F [1°C] under standard conditions, and there are …

Why open ocean has lowest net primary productivity?

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.
