Vedclass · Answer

(B) The term $	ext{PAR}$ stands for $	ext{Photosynthetically Active Radiation}$.It represents the spectral range of solar radiation from $400 	ext{ nm}$ to $700 	ext{ nm}$ that photosynthetic organisms are able to use in the process of photosynthesis.Out of the total incident solar radiation reaching the Earth's surface,less than $50 \%$ is $	ext{PAR}$.Therefore,the correct option is $B$.

What is the percentage of $\text{PAR}$ in the incident solar radiations?
