As the diet of herbivores contains a lot of cellulose, which is difficult to digest, the alimentary canal of the herbivores becomes a much longer system. The food which they consume offers very little level of energy and lower proteins. The basic process of the koalas digestive system functions in the similar way like the usual digestive system of the other animals (most of them). However, there is less food (Eucalyptus Leaves) for Koalas in Queensland, and therefore, the population is less also. Climate change is also contributing to the decline of koalas. Koalas have the key ability to regulate their body temperature. The process of digestion begins with the mouth and the intake of food.
