K is the carrying capacity, r is the intrinsic rate of growth, and h, the harvest rate,
parameter. Sketch the bifurcation diagram for this system. Be sure
to identify the stability of each branch of your bifurcation diagram. For what
value of h is there a bifurcation? What kind of bifurcation is this? Describe the
long-term behavior of the fish population for harvest rates on either side of this bi-
furcation. Is there something wrong with this model?
