It is estimated that the net amount of carbon dioxide fixed byphotosynthesis on the landmass of Earth is 5.5 * 1016 g>yrof CO2. Assume that all this carbon is converted into glucose.(a) Calculate the energy stored by photosynthesis onland per year, in kJ. (b) Calculate the average rate of conversionof solar energy into plant energy in megawatts, MW11W = 1 J>s2. A large nuclear power plant produces about103 MW. The energy of how many such nuclear power plantsis equivalent to the solar energy conversion?Integrative Exercises
