Explain differences between exponential growth and logistic growth.

Answer: So the difference between exponential growth and logistic growth is that Exponential growth model is one that exists when the the rate of growth is proportional to the existing amount. For this, a population need ideal conditions: bacteria in a petri dish, radioactive decay or compound interest in a saving amount. The logistics is a different kind of behavior which is more realistic to population not in ideal conditions: the rate of growth is proportional to the amount but there is also a damping factor due to competition and limited resources. This model works that at first the rate of growth getting faster then it slows down since there are too many individual competing on limited space. When this population reaches its equilibrium state, the rate of growth is zero and if there will be no interruptions, the size of the population will stay constant.

The biggest difference, however, is that the line in the logistic growth graph changes direction and begins to level off as it nears the carrying capacity. That means that the main difference between exponential and logistic growth is that logistic growth takes into account carrying capacity.
