Final answer:
It is referred to as coprophagy.
Step-by-step explanation:
B). coprophagy. Coprophagy is a behavior observed in certain animals, such as rabbits, where they consume their own feces to obtain additional nutrients that were not fully extracted during the initial digestion process.
For example, the rabbit's cecum, a projection off of the colon, contains bacteria that can digest vegetable matter more thoroughly, producing important nutrients like vitamins. By engaging in coprophagy, the rabbit is able to recycle these nutrients and obtain maximum nutrition from its food.
This behavior is observed in certain animals, like rabbits, who consume their own feces to obtain additional nutrients that were not fully digested during the initial round of digestion.
