Assume that N(t) denotes the density of an insect species at time t and P(t) denotes the density of its predator at time t. The insect species is an agricultural pest, and its predator is used as a biological control agent. Their dynamics are given below by the system of differential equations. Complete parts (a) through (c). dN = 7N - 5PN dt dP = 4PN - P dt ..... (a) Explain why dN = 7N describes the dynamics of the insect in the absence of the predator. dt If there are no predators present, then P(t) = for all t. Substitute P = in the given differential dN equations to get dt So in the absence of the predators, the above equation describes the dynamics of the insect population. dN Solve the equation, dt N(t) = (Type an expression using t as the variable.) Describe what happens to the insect population in the absence of the predator. In the o boone dotor tho in uletion
