The equation of Verhulst-Pearl logistic growth is $\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}\left[\frac{\mathrm{K}-\mathrm{N}}{\mathrm{K}}\right]$.

From this equation, $\mathrm{K}$ indicates:

Assertion : In sigmoid growth curve, population finally stabilizes itself.

Reason : Finally, the death rate increases than the birth rate.
