Discuss the factors affecting population growth that can result in an exponential growth curve.

a. exponential growth occurs in ideal/unlimited environment 

b. population growth determined by natality, mortality, immigration and emigration 

c. natality / births / reproduction increases population
OR
number of reproducing individuals determine the rate of growth 

d. as long as natality is higher than mortality 

e. low mortality leads to exponential growth 

f. absence of limiting factors will lead to exponential growth 

g. «limiting factors» could be «competition for» resources/habitat / presence of predators/diseases 

h. higher mortality and/or emigration compared to natality and/or immigration cause population to decrease/rate of growth to slow
