3. Suppose that a lizard species eats only one type of insect and the populations follow Lotka-Volterra dynamics. The intrinsic growth rate of insects in the absence of predators is 0.2 per week, and the mortality rate of the lizards in the absence of insects is 0.05 per week. The capture efficiency rate is 0.002, and the efficiency at which insect biomass is converted into predator biomass is 0.2. Draw a phase plane plot of lizards interacting with these insects. Indicate the following information on the phase plane plot. a. Draw and label the insect zero growth isocline. (Be sure to indicate the population size). b. Draw and label the lizard zero growth isocline. (Be sure to indicate the population size). c. If the population of insects start with 75 insects and 125 lizards, what will be the trajectory of each species? d. Draw the long-term population trajectories.
