Oceans are least productive because:
(i) There is insufficient radiation as sunlight decreases with the increasing depth of the ocean.
(ii) Oceans are nitrogen deficient which is an important nutrient for plants.
(iii) Conditions of high salinity in ocean are not favourable for all plants.
(iv) There is no substratum to support plants.
