Predator has carrying capacity

Following some observation are given

The number of prey, N, increase at low predator densities, P, and decrease at high predator densities

Prey zero isoclines is depends on the ratio of the growth rate of prey to the capture efficiency of the predators

 Number of predator needed for prey isoclines is depends on the ratio of the death rate of predators to the conversion efficiency of predators

Number of predator for prey isoclines depends on the ratio of the death rate of prey to the conversion efficiency of predators

For two species A and B in competition, the carrying capacities, competition coefficients, per capita growth rate and population size are

KA = 1000           KB = 1200    α of B= 1     β of A= .5       rB= .5         r A= .3                

AN= 500                  BN= 200
