What you’ll learn

ExponentialExplain how a constant positive per-capita rate produces exponential population growth and recognize the model’s limits.Exponential growth follows dN/dt = rN: as population size increases, the total growth rate increases, producing a J-shaped curve under temporarily plentiful-resource conditions.

Questions this course answers

What does r describe in dN/dt = rN?

r is the rate of increase per individual.

Why does an exponential-growth curve become steeper?

With a constant positive per-capita rate, more individuals produce a larger total increase.

Why is exponential growth usually a limited-interval model in nature?

Finite resources and other limits eventually break the constant-rate assumption.
