Less than 50 % of the solar energy incident over earth is PAR (photosynthetically active radiation).

Q. Percentage of photosynthetically active radiation $(P A R)$ in the incident solar radiation is

$1 - 5%$

$2 - 10%$

less than $50%$

approx. $100%$

Less than $50%$ of the solar energy incident over earth is $P A R$ (photosynthetically active radiation).
