Final answer:
The structure of a molar tooth is adapted for grinding and crushing food. The large flat surface area with cusps increases the efficiency of chewing. The outer layer of enamel provides protection against wear and tear.
Step-by-step explanation:
The structure of a molar tooth is highly adapted for its function of grinding and crushing food. The molar tooth has a large, flat surface area with irregular ridges called cusps that help in the breakdown of food. These cusps increase the efficiency of chewing by increasing the contact area between the teeth and the food. The molar tooth also has an outer layer of hard enamel, which is the hardest substance in the human body, providing protection against wear and tear.
