The figure below shows population cycles of snowshoe hare and lynx. recent field studies suggest that the most likely explanation for these cycles is
(a)periodic winter storms.
(b)predation of snowshoe hares by a combination of lynxes, foxes, and owls.
(c)nearly unlimited food for hares during the summers.
(d)boom and bust cycles in lemming populations.
(e)excessive predation of snowshoe hares by lynxes.
