Logistic growth describes a population's increase that starts rapidly but slows as it approaches a maximum limit, known as the carrying capacity. This model is often represented by an S-shaped curve, where the population grows quickly at first, then gradually levels off as resources become limited. In nature, many species, such as deer or bacteria, exhibit logistic growth patterns. Initially, when resources are abundant, populations can grow exponentially. However, as competition for food, space, and other resources increases, the growth rate declines, stabilizing the population size over time.
