What is the function of the inner ear in rabbits?

The function of the inner ear in rabbits, as in many vertebrates, is crucial for both balance and hearing. The inner ear contains structures known as the cochlea and the vestibular system. The cochlea is responsible for converting sound vibrations into neural signals that can be interpreted by the brain, facilitating the sense of hearing. The vestibular system comprises fluid-filled canals and sensory structures that help maintain balance and spatial orientation. This dual role is essential for navigating their environment, avoiding predators, and effectively communicating with other rabbits through sounds.

The other options address functions not associated with the inner ear. For example, digestion is a process handled by the gastrointestinal system, not the inner ear. Body temperature regulation is managed through different physiological mechanisms and bodily systems, while sound production is typically performed by vocal cords or similar structures, rather than the inner ear itself.
