AP Environmental Science Primary Productivity Problems Net Primary Productivity efficiency can be calculated for terrestrial producers when values for insolation energy, respiration loss and gross productivity are known. Use the equations below to answer the following problems: Net Primary Productivity = Gross Productivity – Respiration Loss Efficiency = . NPP . X 100 Insolation Energy In a rice paddy in Southeast Asia, the insolation energy is 6,000,000 calories/m2/day. The gross productivity of the rice is 0.012 grams/cm2/day, and the respiration loss is 20 percent. One gram of rice is equivalent to 1000 calories. Calculate the net primary productivity of the rice. Find the efficiency of photosynthesis by the rice. Could you mostly help me set it up and find it? So I can learn how to do it.
