Consider the system dr dt x x 1 y dy dt where and y denote the sizes of two interacting populations 1 1 How does the species and they species respectively behave in the absence of the othe species 1 2 Describe the type of interaction between the two species e g competition predator prey etc 1 3 Draw the phase diagram note that phase diagrams drawn by an automated plotter will b awarded zero and use it to predict the outcome of the system if initially to 2 yo 2 y x 2
