In the natural world survival is usually dependent on the fitness of the animal. For it to remain fit it must consume enough energy to function (starvation etc. can occur if it does not). Thus, if needed, animals may view members of their own species or even populations as food sources.
Other animals consume their mating partner after they fertilize since they serve no purpose and the energy requirement in pregnancy is very high.
Either way, cannibalism in animals is usually due to the requirement of a food source when all other common sources are unavailable.
