#Section 2: Evolution
dN/dt = rN (K-N/K ) The logistic equation above is used to describe the rate of change of a population, N, with time, t, Where r is the intrinsic rate of increase and K is the carrying capacity. What is value of per capita growth rate when population size is 200 individuals? ( K= 400, r =.25)
