4. (15 points) A more realistic model of population growth is the logistic model, given by: 3% $k+1 : 33k + (2171.: (1 - E) where Q is represents the growth rate absent environment constraints. Let 5% represent the population in thousands. Assunne that 3:0 2 2D and Q = 0.25. (a) If M : 100. what is the population after 25 generations? (1)) If M : 200. what is the population after 25 generates? (c) What does the parameter M seem to represent
