Biologists stocked a lake with 160 fish and estimated the carrying capacity (the maximal population for the fish of that species in that lake) to be 4,000. the number of fish tripled in the first year. (a) assuming that the size of the fish population satisfies the logistic equation, find an expression for the size of the population after t years. (b) how long will it take for the population to increase to 2000 (half of the carrying capacity)?

There is considerable evidence to support the theory that for some species there is a minimum population m such that the species will become extinct if the size of the population falls below m this condition can be incorporated into the logistic equation by introducing the factor(1-(m/p)) thus the modified logistic model is given by the differential equationdp/dt = kp (1- (p/k)) (1-(m/p))where k is a constant and k is the carrying capacity.suppose that the carrying capacity k = 1 the minimum population m = 800 and the constant k = 0.05
