a) Photosynthesis is estimated to produce 330.0 g (dry weight) of plant matter per square meter, 50% of which is carbon. Calculate the total number of grams of carbon "fixed" each year by 1000 square meters.
b) The photosynthetic reaction can be represented as: 6CO2 + 6H2O -> C6H12O6 + 6O2. Of the glucose produced, 20.0% is used by the plant to fuel respiration; the rest is converted to plant matter. Calculate the total moles of glucose produced annually in our reference 1000 square meter area.
c) Each mole of glucose produced represents the absorption of 2803 kJ of solar energy. If the average energy available from the sunlight over an eight-month period is 1.3 kJ/cm2 per day, what percentage of the incident solar energy is converted to chemical energy in our 1000 square meter area?
