Which sense is described as being most critical to the warthog's survival and feeding habits?

Answer

Olfactory sense, indispensable for locating subterranean food sources

Although the warthog possesses sharp hearing, aided by tufts of hair on its moderately sized ears that help funnel sound, and adequate eyesight for spotting distant predators, its most indispensable sense for securing sustenance is its sense of smell. The elongated snout terminates in a broad, tough muzzle perfectly engineered for rooting. This keen olfactory sense allows the warthog to successfully locate underground resources such as bulbs, roots, and invertebrates, which are essential dietary components, especially in environments that experience seasonal dryness.
