Photosynthesis in Higher Plants
Solution:
According to Blackmans law of limiting factor, at any
given time photosynthesis can be limited either by light or
$CO_2$. Blackman proposed the law of limiting factors in $1905$

law, when a process depends on a number of factors, its
rate is limited by the pace of the slowest factor.
