The important concept of exponential growth is that the population growth rate, the number of organisms added in each reproductive generation, is accelerating; that is, it is increasing at a greater and greater rate.
The simplest type of population growth is exponential, as shown by reindeer on Pribilof Islands for 30 years after introduction. Exponential growth occurs when a single species is not limited by other species (no predation, parasitism, competitors), resources are not limited, and the environment is constant.
The simplest models describing population size are exponential growth and logistic growth, which assume: − constant food and resource availability − a constant environment − no interactions with other species − no disease The exponential model also assumes no competition among the members of a species for the available resources ...
The Exponential Equation is a Standard Model Describing the Growth of a Single Population. The easiest way to capture the idea of a growing population is with a single celled organism, such as a...
The yearly increase in the northern YNP bison population between 1902 and 1915 can be described as exponential growth. A population that grows exponentially adds increasingly more...
While the details of the population growth patterns vary between the species, each shows the characteristic exponential pattern of initial slow growth when the population size is small, and more rapid growth as the population size increases.
