Of the total incident solar radiation the proportion of PAR is

A

about 60%

B

less than 50%

C

more than 80%

D

about 70%

Text Solution

Verified by Experts

The correct Answer is:
B
PAR (photosynthetically active radiation) designates the spectral range of solar radiation from 400-700nm that photosynthetic organisms are able to use in the process of photosynthesis. Of the total incident solar radiation the proportion of PAR is less than 50%.
