(1 point) In Example 1 we used Lotka-Volterra equations to model populations of rabbits and wolves....
A previous exercise modeled populations of aphids and ladybugs with a Lotka-Volterra system. Suppose we modify those equations as follows: · = 3A(1 – 0.00025 A) – 0.04AL dL = -0.9L + 0.0003 AL dt (a). Find the equilibrium solutions. Enter your answer as a list of ordered pairs (A, L), where A is the number of aphids and L the number of ladybugs. For example, if you found three equilibrium solutions, one with 100 aphids and 10 ladybugs, one...

(1 point) Populations of aphids and ladybugs are modeled by the equations - 1A – 0.01AL dA dt dL == -0.6L + 0.004AL dt (a). Find the equilibrium solutions. Enter your answer as a list of ordered pairs (A, L), where A is the number of aphids and L the number of ladybugs. For example, if you found three equilibrium solutions, one with 100 aphids and 10 ladybugs, one with 200 aphids and 20 ladybugs, and one with 300 aphids...

Exercise 3, Section 9.5. Modified Lotka- Volterra Predator-Prey model Consider two species (rabbits and foxes) such that the population R (rabbits) and F (foxrs) obey the system of equations dR dt dF dt R2-R)-12RF . What happens to the population of rabbits if the number of foxes is arro? (Use the phase line analysis from Chapter 2) What happens to the population of foxes if the number of rabbits is zero? 3. Using the method of nullclines, draw an approximate...
