The Snowshoe Hare is the Lynx's main food source, so the two species are very interactive and dependent. When the hare is scarce, the Lynx feeds on mice, voles, squirrels, and carrion, but these animals do not sufficiently meet the lynx's needs and make the lynx more vulnerable to starvation or predation. Thus, when hare population dwindles the lynx population also decreases. After some time passes, the hare  population increases again because of less predation from the lynx. This repeated cycle becomes a perpetual pattern that can be found in most predator-prey relationships.
