Deer are part of  food chains and webs in nature. They are herbivores or primary consumers. These ruminants graze on a variety of plants and digest this material in their four chambered stomach. Carnivores are consumers that eat animal flesh. A deer is a prey animal that is hunted by carnivores. Wolves can eat deer. However, many wolves have been driven to almost extinction in most states in the United States. However, it has been shown that wolves help keep the deer population in check by hunting and feeding on deer, usually older, younger, weak or sick ones that they can catch. This keeps the population at levels the ecosystem can support in terms of resources and space. When predators like wolves are removed from the ecosystem, deer experience a population explosion due to lack of predation. Then, due to competition for limited resources, the deer experience a die- off due to starvation.  Deer are an important part of nature. Deer are used for transportation, food(venison) and clothing.
