Solution
The correct option is B Depth of water in meters
Net primary productvity is the measure of biomass available for the heterotrophs after meeting the cost of respiration and maintainance by the producers.The measure of NPP depends on the number and efficciency of autotrophs to store energy in the form of biomass. In the given graph it indicates a gradual decrease in the measure of NPP in an aquatic ecosystem.The gradual decrease indicates the decrease in the number and efficicency of autotrophs at deeper depths of the system. Thus Y axis in the graph indicates depths of water in meters.
