Following figure are shown figure of predator prey model
Following some observation are given
A) The number of prey, N, increase at low predator densities, P, and decrease at high predator densities
B) Prey zero isoclines is depends on the ratio of the growth rate of prey to the capture efficiency of the predators
C) Number of predator needed for prey isoclines is depends on the ratio of the death rate of predators to the conversion efficiency of predators
D) Number of predator for prey isoclines depends on the ratio of the death rate of prey to the conversion efficiency of predators
Which of the above observation are true?

#Section 2: Evolution
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
According to the Lotka-Volterra model, what is growth rate of species A?
