Assume there is a certain population of fish in a pond whose growth is described by the logistic equation. It is estimated that the carrying capacity for the pond is 1300 fish. Absent constraints, the population would grow by 200% per year. If the starting population is given by Po = 600, then after one breeding season the population of the pond is given by P1 = After two breeding seasons the population of the pond is given by P2 =
