Gross Productivity - Total amount of Glucose produced by the producers.

Net Productivity - G.P. - Amount of Glucose metabolized by the producers, food energy available to consumers.
 

Initial = 0.8 mg/L of oxygen  
Dark = 0.3 mg/L
Light= 0.9 mg/L                                     
     

                                   

                                                                                 
                                     Initial-Dark = 0.5 = Respiration Rate = 0.5/24
                                     Light-Initial = Net Productivity Rate = 0.1/24
                                     Light-Dark = Gross Productivity Rate = 0.6/24
