Vedclass · Answer

(A-D) Oceans are considered the least productive ecosystems due to the following reasons:$(i)$ Insufficient solar radiation: Sunlight intensity decreases rapidly with increasing depth,limiting photosynthesis to the photic zone.$(ii)$ Nutrient limitation: Sea water is often deficient in essential nutrients like Nitrogen and Phosphorus,which are required for primary production.$(iii)$ High salinity: The high concentration of salts in sea water is not favorable for the growth of many plant species.$(iv)$ Lack of substrate: In the open ocean,there is no solid base or soil to support the growth of rooted plants.
