Explanation

The exponential growth can be expressed as
${\ \ \ \ \ \ \ \ \ \ \ W}_{1} = W_{0}\ e^{rt}$ Where, $W_{1}$ = Final size(weight, height, number, etc.) $W_{0}$ = initial size of the beginning of trhe period r = Growth rate t = Time of growth e= base of natural logarithms Here, r is the relative growth rate and is also the measure of the ability of the plant to produce plant material, referred to as efficiency index. Hence, the final size of $W_{1}$ depends on the initial size $W_{0}$.
