The Stock equation is a mathematical equation that describes how a particular variable, such as the population of a species, changes over time. It is also called the "exponential growth model" or the "Malthusian model." The equation is typically written as: Nt = N0 * ert Where: Nt = population size at time "t" N0 = population size at time "0" (initial population size) r = the intrinsic rate of increase (also known as the "per capita growth rate") t = the time interval e = the base of the natural logarithm (about 2.718) The equation shows that the population size (Nt) at any given time (t) is equal to the initial population size (N0) multiplied by "e" raised to the power of the intrinsic rate of increase (r) times the time interval (t). In simple terms, this equation is saying that a population will grow at a steady rate (r) as long as there are enough resources available. If the resources are not enough, the rate of growth will decrease. The stock equation is widely used as a model for population growth, it is also used in the field of economics, ecology and epidemiology. It helps to understand how populations grow over time and how this growth may be affected by different factors such as food availability, predation, and disease.
