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

$J$-shaped growth curve depicts:

Exponential growth of a species can be expressed as:

Comment on the growth curve given below.

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.

Any species growing $A$ under unlimited resource conditions can reach enormous population densities in a short time. Darwin showed how even $B$ growing animal like elephant could reach enormous numbers in absence of check and that characteristics of organism is called $C$. Choose the correct option for $A, B$ or $C$ respectively.
