Density In-Dependent Growth
Population Ranges
Occurs when the growth rate is proportional to the size of the populations.
Logistical growth
Exponential growth
Carrying capacity
Fecundity
Population will have this kind of growth unless some limiting factors (like food, water, space or predation) slows the population growth.
Logistical growth
Exponential growth
Carrying capacity
Fecundity
Population's growth slows or stops following exponential growth, at a population's carrying capacity.
Logistical growth
Exponential growth
Carrying capacity
Fecundity
