For the Verhulst-Pearl Logistic Growth equation $dN/dt = rN \left(\frac{K-N}{K}\right)$,what does $K$ indicate?

Verhulst-Pearl logistic growth is described by the equation:

In India,the human population has a large number of young individuals. This is because of:

Select the correct sequence of phases in the bacterial growth curve.

If the rate of addition of new members increases with respect to the individual host of the same population,then the graph obtained has:

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.
