With the help of suitable diagram describe the logistic population growth curve.
The birth and death rates of four countries are given below. Which one will have the least population growth rate?

$M$ | $15$ | $5$ |
$N$ | $25$ | $10$ |
$O$ | $35$ | $18$ |
$P$ | $48$ | $41$ |
In a population, the condition at which the rate of addition of new members is more than the rate of individuals lost indicates
