Final answer:
Taste and smell are chemical senses that respond to molecules in the food we eat or in the air we breathe.
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, while taste allows animals to discriminate between types of foods.
Both taste and smell are chemical senses because they respond to molecules in the food we eat or in the air we breathe.
