In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity ( K). Exponential growth produces a J-shaped curve, while logistic growth produces an S-shaped curve.

What are the two ways populations can grow?

Population growth can be described with two models, based on the size of the population and necessary resources. These two types of growth are known as exponential growth and logistic growth.
