According to the equation: 1) Species 1 and 2 are: predator and prey 2) Species 1 and 3 are:predator and prey 3) Species 2 and 3 are: Do not interact directly, though they have indirect interaction i.e, compete exploitatively where each has a negative effect through the resources. The equation represented here indicated that all interaction terms are constant.
