Chapter 5, Problem 111AE
It is estimated that the net amount of carbon dioxide fixed by photosynthesis on the landmass of Earth is 5.5 x 1016 g/yrof CO2. Assume that all this carbon is converted into glucose. (a) Calculate the energy stored by photosynthesis on land per year, in kJ. (b) Calculate the average rate of conversion of solar energy into plant energy in megawatts, MW (1 W = 1 J/s). A large nuclear power plant produces about 103WV. The energy of how many such nuclear power plantsis equivalent to the solar energy conversion?
