Explain logistic growth pattern of a population.Why do population growth patterns of all organisms ultimately follow it?
Dear student,Logistic population growth occurs when the growth rate decreases as the population reaches carrying capacity. Carrying capacity is the maximum number of individuals in a population that the environment can support. A graph of logistic growth is shaped like an S. Logistic growth is considered more realistic than exponential as it is assumed that the resources in exponential growth are unlimited and therefore the population grows quickly and is wiped out within a short period of time. For example bacterial culture. However in logistic growth there is a sigmoid growth where the resources are limiting and a plateau is reached after limited growth followed by the death due to lack of nutrients, space and other growth requirements.Regards.
