| What is the percentage of photosynthetically active radiation (PAR) in the incident solar radiation? |
More than 100%.
More than 2-10%. Less than 50%. Less than 10%. |
| Less than 50%. |
| Of the incident solar radiation less than 50 per cent of it is photosynthetically active radiation (PAR). We know that plants and photosynthetic bacteria (autotrophs), fix sun’s radiant energy to make food from simple inorganic materials. Plants capture only 2-10 per cent of the PAR. |
