Final answer:
Rabbits are obligate nasal breathers, meaning they breathe through their nares and not their mouths, which filters and warms the air and allows for efficient oxygen exchange.
Step-by-step explanation:
The rabbit is called an obligate breather because it breathes through both its nares and mouth. This means that the rabbit can take in air through its nose and its mouth to breathe.
Nasal breathing is generally considered superior to mouth breathing as the nasal passages do a better job of filtering particles and warming and moisturizing the air.m Rabbits are obligate nasal breathers, meaning they breathe through their nares and not their mouths, which filters and warms the air and allows for efficient oxygen exchange.
