Exponential growth takes place in Bacteria under ideal conditions. It means a rapid increase in population but actually it is doubling of population in a short time.Under ideal condition generation time of bacteria is just 20 minutes i.e. just after 20 minutes no. of Bacteria is doubled. Initially term used for rapid bacterial growth was logarithmic growthbut that proved to be wrong. Term Exponential growth may also be used for population of higher animals but doubling time is much larger as compared to bacteria.
When the population's resources become less available.
Just before the crusaders there was an exponential population growth. Many reasons can be given, main ones being 'Driving away the Islam', 'Crusading would counter this growth and would cause the population to lower again', 'The ownership of Jerusalem',...
A major burden to the growth of China's economy was cause by the high population growth. An increase in the population has resulted into limited resources among the residents.
Animals that reproduce quickly and have short gestation periods, such as rabbits, rodents, and insects, are known to cause population growth because they can produce many offspring in a short amount of time. These animals can quickly outpace their predators and competitors if conditions are favorable, leading to rapid population growth.

when a predator developes a population growth increase, its prey will be over-hunted and could cause premature extinction

yes
overpopulation
the prison becomes overcrouded and could cause riots and rebellions
