The Lotka-Volterra model is often used to characterize predator-prey interactions. For example, if R is the population of rabbits (which reproduce autocatlytically), G is the amount of grass available for rabbit food (assumed to be constant), L is the population of Lynxes that feeds on the rabbits, and D represents dead lynxes, the following equations represent the dynamic behavior of the populations of rabbits and lynxes: R+G→ 2R (1) L+R → 2L (2) (3) Each step is irreversible since, for example, rabbits cannot turn back into grass. a) Write down the differential equations that describe how the populations of rabbits (R) and lynxes (L) change with time. b) Assuming G and all of the rate constants are unity, solve the equations for the evolution of the animal populations with time. Let the initial values of R and L be 20 and 1, respectively. Plot your results and discuss how the two populations are related.
