For a given species, the maximum rate which shows increased per individual under the ideal condition is the Biotic potential.

Biotic potential is termed as the unrestricted growth of population which results in a maximum growth of the population. It is well known as the possible vital index of a species. When there is the highest birthrate in a species it has the lowest mortality rate.
In biotic potential shows the ability of a population of living species to increase under ideal environment condition. There are no predators, sufficient food supply and lack of disease.
