If natality rate is parallel to mortality rate then population
Slowly increases
Remains stationary
Shows $J$-shaped curve
Slowly decreases
The growth of population is determined by
$A $: Under unlimited resource condition a population can show a exponential growth curve.
$R$ : $A $maximum possible number of individuals can always be supported when enough resources are available
The formula for exponential population growthis
In the exponential growth equation $\mathrm{N}_{\mathrm{t}}=\mathrm{N}_{0} \mathrm{e}^{\mathrm{rt}}$, $e$ represents :
