Document Summary
Population can grow exponentially when conditions are favourable, but exponential growth cannot continue indefinitely. Population grow rapidly: when individuals leave an average of more than one offspring over substantial periods of time. Rapid increase in population size can be in two forms: 1) geometric growth, 2) exponential growth. A) geometric growth: populations grow geometrically when reproduction occurs at regular time intervals, reproduce in synchrony at regular time intervals. =discrete time periods: species population increase size in constant proportion. Number of individuals added to the population- increases with each time period. Each year after- will have more individuals being added. Will have descrite set of points- not a completely curved line instead will have points that rise up to exponential growth. Able to predict population size after any period of time. B) exponential growth: population grow exponentially when reproduction occurs continuously, people usually not reproduce in synchrony- at discrete time periods.
