2. The figure below shows the interaction between predator abundance and prey abundance. Populations of lynx and hares are located at the star. Based on the Lotka-Volterra predator-prey model, we would expect the number of prey to and the number of predators to Predator abundance (P) Pisocline Nisocline Prey abundance (N)

Draw and label graphs (including zero-growth isoclines) showing the predicted behavior of the Lotka-Volterra predator/prey equations if we assume prey growth follows and exponential growth model. Show how the graphs would change of the prey follow a logistic growth model.
In the Lotka-Volterra predator-prey equations, the term a b N prey N predator describes: The rate at which predators eat prey The rate at which new predators are added to the predator population The rate at which the predator population increases over time The intrinsic growth rate of the prey population
The relationship between predator and prey populations has been studied by computer simulation using equations which form part of a mathematical model devised by Lotka and Volterra. The data in Table 6.10 show the results of such a simulation when the prey population begins with 20 individuals and the predator population begins with six individuals. 1.Explain why the peaks in the predator population occur after those in the prey population. 2. This simulation assumes one prey species and one predator species in an imaginary ecosystem and is based on mathematical equations. Why is it likely to be too simplistic to describe accurately what happens in nature?
With respect to the Lotka-Volterra predator-prey model, which of the following statements is most likely true? Under this model, it is possible for a predator to drive its prey to extinction. All of the statements are true. Non of the statements is true. This model predicts neutrally-stable predator-prey cycles, as opposed to a stable equilibrium. O In this model, an increase in searching efficiency (a) will increase the maximum prey population.

Are the sun and the sh density dependent or density independent factors? (Try to find the priority information here, there are some distractor Think about your definitions for the words below.) A. density dependent B. density independent 13. Which of the following statements is correct? A. Population size of predators increases when their prey's population is low. B. Competition for resources is density-independent when food is plentiful. C. Discase is density-dependent because spreading occurs more easily when a population is closer together. D. A change in average temperature is a density-dependent factor because fewer organisms can acclimate to variations in temperature.
