Why is logistic growth more realistic than exponential growth?

Question

Julian Aguilar · Accepted Answer

The exponential growth is totally irrealistic because it doesn't consider the environmental limits that have consequences on the population, according to this model, a population can grow with no limits.

The logistic growth is more realistic because it considers those environmental limits that are density, food abundance,resting place, sickness, parasites, competition.... It tells us that the population has a limit because of those environmental factors.

For example, if you study a rabbit population on a field, without predators of course, this population will reach a maximal nomber of individuals, because of the lack of food, the mixomatosis, parasites, intra and inter specific competition ...

Hope it's helpfull :)

undefined Logistic growth is more realistic than exponential growth because it takes into account limiting factors such as resource availability and environmental carrying capacity, which eventually slow down the rate of growth. Exponential growth assumes unlimited resources and does not account for constraints on population growth.
