The life history pattern in which population growth is logistic is known as the logistic growth model. This model describes how populations initially grow exponentially, but eventually reach a carrying capacity where growth levels off due to limited resources or other constraints. The logistic growth model is often represented by an S-shaped curve.
Ecological model
1. Is based on the geometric model of population growth 2. Does not incorporate density dependence 3. Extend model to two species-populations
Yes, an ecological model can consist of a mathematical formula. Mathematical equations are often used in ecological models to represent relationships between different variables, such as population dynamics, predator-prey interactions, or nutrient cycling. These formulas can help researchers understand and predict how ecosystems may respond to different environmental changes or disturbances.
