Population models are mathematical representations used to describe how populations of organisms change over time. These models help scientists understand factors like birth rates, death rates, and migration patterns. By simulating different scenarios, researchers can predict how populations will grow or decline under various conditions. There are several types of population models, including the exponential model and the logistic model. The exponential model assumes unlimited resources, leading to rapid growth, while the logistic model accounts for environmental limits, resulting in a more gradual increase until reaching a carrying capacity. These models are essential for wildlife management and conservation efforts.
