Solution
The correct option is A 2 %
Most of the energy of sun that falls on earth is reflected and scattered. Plants absorb only a small fraction of the energy and out of that also they lost a lot of energy as radiation and actually convert only a small fraction of the absorbed energy (2 %) into organic molecules or biomass. Therefore, the correct answer is option A.
