The correct option is C 170 billion tons
The annual net primary productivity is the available biomass for the consumption to heterotrophs (herbiviores and decomposers) in a year. The annual net primary productivity of the whole biosphere is approximately 170 billion tons dry weight of organic matter. Out of this, oceans contribute 55 billion tons.
