In the previous topic, you looked at
the most simple model developed to describe population
growth: the exponential model. 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.
Don't forget, though, that even this model simplifies
the true complexities found in population biology.
