Exponential Population Growth
Captions available
The idea
Exponential growth occurs when a population's per capita growth rate stays constant regardless of population size, producing accelerating growth that traces a J-shaped curve over time.
In practice
A bacterial population dividing at a fixed rate in unlimited nutrient media doubles again and again, producing a J-shaped growth curve.
Where people slip
Exponential growth requires effectively unlimited resources — no real population sustains it indefinitely.
