Work out population growth (exponential) instantly with clear inputs, formula shown and shareable results.
Applies the continuous exponential growth model, in which the intrinsic rate of increase acts on the whole population at every instant.
Exponential growth
N(t) = N0 x e^(rt); doubling time = ln 2 / r
Only when resources are effectively unlimited, such as early colonisation or a bacterial culture in fresh medium.
Geometric growth uses discrete breeding seasons with a finite rate lambda; exponential growth is continuous.
