In exponential growth, a population's per capita (per individual) growth rate stays the same regardless of population size, making the population grow faster and faster as it gets larger in nature, populations may grow exponentially for some period, but they will ultimately be limited by resource availability.
Population growth the increase in a population that occurs when the birth rate is higher than the death rate, or when immigration exceeds emigration, or when a combination of these factors is present a growth curve, obtained by plotting population size against time, is typically s-shaped (sigmoid) or j-shaped (see graph.
