The formula of growth rate for population in a given time is

Environmental resistance includes which of the following factors?

Given below are two statements:
Statement-$I$: $A$ population growing in a habitat with limited resources shows initially a lag phase.
Statement-$II$: $A$ population growing in a habitat with limited resources shows finally an asymptote phase.

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:

With the help of a suitable diagram,describe the logistic population growth curve.

In a population,unrestricted reproductive capacity is called
