What characterizes the logistic growth model in populations?

The logistic growth model is characterized by an initial phase of rapid, exponential population growth that occurs when resources are abundant and environmental conditions are favorable. As the population grows and approaches the carrying capacity of its environment—defined as the maximum number of individuals that can be sustained—the growth rate begins to slow. This deceleration occurs due to limitations in resources such as food, space, and other environmental factors that lead to increased competition among individuals.

In this model, the interaction between the population size and the carrying capacity results in a characteristic S-shaped curve when graphed over time. Initially, growth is exponential because there are plenty of resources available, but as the population nears its carrying capacity, factors such as limited resources and increased competition lead to a decrease in the growth rate. Ultimately, the population stabilizes around the carrying capacity, illustrating how growth is limited by environmental constraints.

This understanding of the logistic growth model highlights that it describes a more realistic scenario for many populations, which do not grow indefinitely and are influenced by various biotic and abiotic factors in their ecosystem. The other options present concepts that do not accurately reflect the dynamics of the logistic growth model, focusing instead on continuous growth or immediate declines without considering the gradual nature of population adjustments in response to carrying
