Biological logistic growth

WebWhen resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce, and it levels off when the carrying capacity of the environment is reached, … WebAnd obviously, we know that's not realistic. Now with logistic growth, I'll do this in red, in logistic growth, in the beginning it looks a lot like exponential growth, it's just a little bit slower. But then as the population gets higher and higher, it gets a good bit slower, and it's limited by the natural carrying capacity of the environment ...
