Consider two populations of animals that compete with each other in the same environment. Either population alone would expand to the limits of the environment, but together each population exerts a negative influence on the other. This is represented by b x b y d x d y (-) (-) y x Assume also that: Birth rate of species x is b x = 0 . 02 animals per month. Birth rate of species y is b y = 0 . 05 animals per month. Death rate of species x is d x = 0 . 00003 x animals per month. Death rate of species y is d y = 0 . 00009 y animals per month....
