Human population growth in India is:

In a forest, there are initially $100$ deer. Over a certain period, $30$ are born and $10$ die. Assuming food is abundant and predators are few, calculate the intrinsic rate of natural increase for that population.

Exponential growth curve is:

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: The logistic growth model of populations is considered more realistic than the exponential growth model.
Reason $R$: Resources are finite.
In the light of the above statements, choose the most appropriate answer from the options given below:

The exponential growth equation is $N_{t} = N_{0}e^{rt}$,where $N_{t}$ is the population density after time $t$. What do $N_{0}$ and $r$ refer to,respectively?

The equation $\frac{dN}{dt} = rN \left(\frac{K - N}{K}\right)$ represents which of the following?
