Answer
The growth of living organisms in their natural environment is characterised by an S-shaped curve called sigmoid growth curve. This curve is divided into three phases – lag phase, log phase or exponential phase of rapid growth, and stationary phase.
$\text{W}_1=\text{W}_0\text{e}^{\text{rt}}$
Where,
W1 = Final size
W0 = Initial size
r = Growth rate
t= Time of growth
e = Base of natural logarithms
