The capacity of the environment in which a species can get maximum nutrition is called:

$A$: Environmental resistance operates to slow down the exponential phase in logistic population growth.
$R$: $A$ crash phase does not occur in this population.

Two opposite forces operate in the growth and development of every population. One of them relates to the ability to reproduce at a given rate. The force opposite to it is called:

The statement 'Food supply increases in an arithmetic progression,while population tends to increase in a geometric progression' was proposed by:

In which of the following is exponential growth observed?

In a hypothetical population of $100$ individuals with an intrinsic rate of increase $(r)$ of $0.5$ per female per year,if the population exhibits exponential growth,what will be the population size after $6$ years? (Given $e = 2.72$)
