The graph in exponential growth will be

The integral form of the exponential growth equation as $N_{t}-N_{0} e^{r t}$

$A.$ Population density after time $t$

$B.$ Population density at time zero

$C.$ Intrinsic rate of natural increase

$D.$ The base of natural logarithms $(2.71828)$

Identify $A, B, C$ and $D$ from the given equation

If birth rate is $100 ,$ death rate is $10$ and number of individuals in population group is $1000 ,$ then what will be the percentage of natural growth rate?

Below diagram indicates

Change in population size equation with prolonged exponential phase can be converted into logistic growth equation by multiplying it with
