| '''Biological exponential growth''' is the exponential growth of biological organisms. When the resources availability is unlimited in the [[habitat]], the [[population]] of an [[organism]] living in the habitat grows in an [[Exponential growth|exponential]] or geometric fashion. | |
| | |
| Resource availability is obviously essential for the unimpeded growth of a population. Ideally, when resources in the habitat are unlimited, each species has the ability to realise fully its innate potential to grow in number, as [[Charles Darwin]] observed while developing his theory of [[natural selection]].
| |
| | |
| If, in a hypothetical population of size ''N'', the birth rates (per capita) are represented as ''b'' and death rates (per capita) as ''d'', then the increase or decrease in ''N'' during a time period ''t'' will be:
| |
| | |
| <math>dN/dt=(b-d)N</math> | |
| | |
| (b-d) is called the 'intrinsic rate of natural increase' and is a very important parameter chosen for assessing the impacts of any biotic or [[Abiotic components|abiotic factor]] on population growth.
| |
| | |
| Any species growing exponentially under unlimited resource conditions can reach enormous [[Population density|population densities]] in a short time. Darwin showed how even a slow growing animal like the [[elephant]] could reach an enormous population if there were unlimited resources for its growth in its habitat.
| |
| | |
| If birth giving takes two parents we get [[Nurgaliev's law]].

I would like to introduce myself to you, I am Jayson Simcox but I don't like when people use my full title. For years he's been living in Alaska and he doesn't strategy on changing it. She works as a travel agent but soon she'll be on her personal. I am truly fond of to go to karaoke but I've been using on new issues recently.
