Shelford's law of tolerance is a principle developed by American zoologist Victor Ernest Shelford in 1911.
It states that an organism's success is based on a complex set of conditions and that each organism has a certain minimum, maximum, and optimum environmental factor or combination of factors that determine success.
[1] The further elaboration on the theory of tolerance is credited to Ronald Good.
In case of chemical reactions it is known as law of limiting factor.
