Why productivity of oceans are less than the terrestrial productivity?
The productivity of an ecosystem depends on the extent of solar radiation, availability of nutrients, precipitation, soil type, temperature, producer’s photosynthetic efficiency and other environmental factors. The availability of light and mineral nutrients is very in the oceans as compared to the terrestrial habitat. Primary productivity of organic material in the oceans is very low. Also, Producers in oceans are algae, having less efficient ability for carbon fixation, they have less surface area to capture sunlight. As a result, the productivity of oceans is less than the terrestrial productivity.
