You can simplify the logistic growth model by defining a new variable x to represent the portion of the population that’s alive, compared to the total population that the environment could support (and keep alive). So with x = N/K, you get a new differential equation in terms of x. Now we are looking at the rate of change of the population fraction over time. controversy\u0027s ri https://cmctswap.com
