The percentage of solar radiation absorbed by all the green plants for the process of photosynthesis is about
(a) 1 %
(b) 5 %
(c) 8 %
(d) 10 %
(a)
The green plants capture about 1% of the energy of sunlight that falls on their leaves for photosynthesis. This is so because photosynthesis is possible only with a very few frequencies in the visible light. So, only 1% of the energy of sunlight that falls on their leaves is captured and converted into food energy.
Therefore option (A) is correct
