Question

In old growth forest of Douglas Fir, (type of a tree), the spotted owl dines mainly on flying squirrels. Suppose the predator-pry matrix for these two population is 6 0.1 0.3 -0.275 1.8 1:3] 12= , 11 = 1.75, 12 = 0.15 P1= [^] 2 11 P2 Xo Find the long term population's of the owls and squirrels growth rate. a. The population of owls will decrease to zero at a rate of 60% while the population of rats will increase indefinitely, this is a flaw in closed ecosystem models. The long term growth of both population of owls and rats is 75% C. The population of owls and rats will reach equilibrium of 11 rats to every 2 owls d. The population of both rats and owls will eventually die out. e. The population of owls and rats will reach equilibrium of 6 rats to every owl
