Final answer:
Taste (gustation) and smell (olfaction) are the most interconnected senses, both involving molecules of the stimulus entering the body and bonding to receptors. They allow animals to sense the presence of food or other animals, and discriminate between different types of foods.
Step-by-step explanation:
Taste, also called gustation, and smell, also called olfaction, are the most interconnected senses in that both involve molecules of the stimulus entering the body and bonding to receptors. Smell lets an animal sense the presence of food or other animals whether potential mates, predators, or prey or other chemicals in the environment that can impact their survival. Similarly, the sense of taste allows animals to discriminate between types of foods.
