Overview
In the previous topic, you looked at the Exponential model, which is the simplest model to describe population growth. While the Exponential model can describe some populations in ideal environments, it is generally too simple. The Logistic model is one step in complexity above the Exponential model. It is more realistic and is the basis for most complex models in population ecology. Please note, however, that even the Logistic model simplifies the true complexities found in population biology.
