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?

In what year was the prey population at its highest? b. i. What was the carrying capacity of the habitat for the predator population in 1855? ii. Compare the carrying capacities for both populations and explain why there is a difference. c. Suggest one factor, other than the presence of prey, that may afieot the size of the predator population. d. The graph shows a predator-prey relationship that is based th a temperate climate.

The black line represents the PREY population, and the grey line represents the PREDATOR population. x-axis for all graphs = Time а. Graph D O b. Graph C С. Graph A O d. Graph B y-axes = Prey or Predator abundance
4. Can you explain why the predator and prey populations do not rise and fall together? What is the reason for the "off-set" nature of the pattern? In general, what population must remain higher for this relationship to be sustainable? Predator or prey?? (A) population size predator prey time (t)
9) If the population of hawks in this area increases, their prey populations might decrease. Later, with fewer prey, the hawk population might decrease. The prey populations might then increase. This is an example of
12. Which of the following dynamics are not predicted by the Lotka-Volterra predator-prey model using an exponential growth function (the simplest form)? a. exponential decline of the predator population in the absence of prey b. coexistence of predator and prey c. exponential growth of the prey population in the absence of predators d. none, all of these are predicted by the predator-prey model e. unstable oscillations in predator and prey density
Think about a predator-prey system that perfectly follows Lotka-Volterra dynamics. The search efficiency parameter (a) represents how quickly the predator finds and kills its prey. What would happen if most the predator population had a parasite that made them less effective predators? Infected animals find and kill prey less frequently (that is, the parasite caused the value of the search efficiency parameter to decline). the populations would still cycle; the amplitude of prey and predator would increase Othe populations would no longer cycle; the prey would increase and the predator would go extinct the populations would no longer cycle; the prey would go extinct and the predator would increase the populations would still cycle; the amplitude of prey and predator would decline the predator and prey populations would no longer cycle; the parasite and the predator populations would cycle instead
Describe the hare-lynx population cycle, considered a classic example of a prey-predator relationship (Figure ). From your examination of the cycle, formulate a hypothesis to explain the oscillations.

1. If a group of predators is added to a community with a population of prey that is growing logisitically and has reached carrying capacity, what will happen to the population of prey over time? a. It will ultimately increase as the prey become healthier due to the presence of predators b. It will drop until all the prey is wiped out c. It will drop, before increasing and then dropping again in a cycle d. It will drop, reaching a new, lower carrying capacity You are testing whether or not there is a difference between the weights of heaitny mke, and those infected with the mouse equivalent of COVID-19.
