Group+10.+Logistic+Growth+2

I. Explanation of what the word means in the context of human population dynamics
Din most real populations both food and disease become important as conditions become crowded. There is an upper limit to the number of individuals the environment can support. Ecologists refer to this as the "carrying capacity" of the environment. Populations in this kind of environment show what is known as logistic growth.

Logistic population growth models density dependent population regulation. The model assumes that when populations increase in size (1) the per capita birth rate decreases (as a result of [|competition] for resources) and/or (2) the per capita death rate increases (as a result of competition for resources, [|predation], or the increased spread of disease). Thus, there is a population size at which the per capita birth rate equals the per capita death rate. At this population size, known as the [|carrying capacity], the [|population growth rate] is equal to zero.
