When Population Growing Logistically?

As competition increases and resources become increasingly scarce, populations reach the carrying capacity (K) of their environment, causing their growth rate to slow nearly to zero. This produces an S-shaped curve of population growth known as the logistic curve

logistic curve
A logistic function or logistic curve is a common S-shaped curve (sigmoid curve) with equation. where , the value of the sigmoid's midpoint; , the curve's maximum value; , the logistic growth rate or steepness of the curve.

When a population is growing logistically at what stage?

Malthus published a book in 1798 stating that populations with unlimited natural resources grow very rapidly, after which population growth decreases as resources become depleted. This accelerating pattern of increasing population size is called exponential growth.

What is logistic growth and when does it occur in a population?

Figure 1. When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth.
