13 give the rates of growth of two populations, x and y, measured in thousands. (a) Describe in words what happens to the population of each species in the absence of the other. (b) Describe in words how the species interact with one another. Give reasons why the populations might behave as described by the equations. Suggest species that might interact in that way. dx dt = 0.01x 0.05xy dy dt = 0.2y + 0.08xy
