The life cycles of parasites are often complex, involving one or two intermediate hosts or vectors to facilitate parasitisation of its primary host. WebThe prey species has an unlimited food supply and no threat to its growth other than the specific predator. If there were no predators, the second assumption would imply that the prey species grows exponentially, i.e., if x = x(t) is the size of the prey population at time t, then we would have dx/dt = ax. WebA key predator of the snowshoe hare is the Canada lynx. The Canada lynx shows a ten-year cycle of abundance that parallels the abundance cycle of hares. As hare numbers increase, lynx numbers do too, rising in response to the increased availability of lynx food. What causes the predator-prey oscillations? all prize bond pakistan
