The logistic growth model is used to predict how a population's size will change over time. In the logistic growth model, N is the starting size of the population, K is the carrying capacity, and r is the intrinsic growth rate. N = rN (1 - x) dN dt The model only considers a single species or population, but species interact with other species in a variety of ways, including competition. To incorporate competition in the logistic growth model, the competition coefficients and are added to the logistic growth model. This results in an equation for each species, which are identified as Species 1 and Species 2. dN dt = r N (1 - N+N2) K1 dN dt = 12 (1 - N+BN1 K2 Will the same effect occur to dN2/dt if is zero? +1
