Sci. text presents two prototypical growth curves for a population: The “J” Curve (for exponential growth) The “S” Curve (for logistic growth) Each curve is drawn from a few base assumptions: The “J” Curve assumes growth rate is constant, and resources are unlimited. Growth occurs at the intrinsic rate of growth (r). So, [...]
