Law of limiting factor is given by

The Law of limiting factors is given by Blackman in 1905. He was a plant physiologist with his study on limiting factors on a plant's photosynthesis system.
As per the law, he stated that several factors regulate the biological process but the factors in different amounts affect the process on the whole.
Like in the case of the process of photosynthesis, the rate of the photosynthesis process is limited by the pace of the slowest factor.
