Path of the system species as \(E_{1}\) (\(E_{2}\)) increases periodically. (a), (b) Path of prey species \(x_{1}\) and predator species y as \(E_{1}\) increases periodically. The other parameter values are given in (7.5). (c), (d) Path of prey species \(x_{2}\) and predator species y as \(E_{2}\) increases periodically. The other parameter values are given in (7.5)
