Not every winter is critical for deer of course. If the winter has light snow£¬ survival and productivity next spring will be high. But if deep snows come and the weather remains cold for several weeks£¬ then the deer must spend more energy to move about£¬ food will be harder to find£¬ and they must then depend more on their fat reserves to pull them through. If such conditions go on for too long some will die£¬ and only the largest and strongest are likely to survive. That is a fundamental rule of life for wild£¬ free wandering animal such as deer.
Yes£¬ life¡ªand death£¬ too ¡ª¡ª is a cycle that goes round and round£¬ and when animals die their bodies become food for other life forms to use by converting them into energy.
And the cycle continues.
