Biology Question on energy flow through ecosystems
Photosynthetically active radiation (PAR) represents the following range of wave length
A
450-950 nm
B
340-450 nm
C
400-700 nm
D
500-600 nm
Answer
400-700 nm
Explanation
Solution
Photosynthetically Active Region (PAR) of solar radiation is visible region. It consist of radiations having wavelength between 400 to 700 nm. Green plants use this wavelength in the process of manufacture of food i.e., photosynthesis.
