What is a Herbivore? The Knowledge Library

The molars of herbivores become worn down by constant grinding of plant material between them. The teeth are composed of softer and harder materials, notably dentine and enamel. The overlying enamel is a hard, resistant layer, especially important in the incisor teeth of rodents. When they first erupt, the molar teeth of herbivores often have.

Many herbivores have hypsodont teeth, including cows and many rodents. A specific case of hypsodonty exists in which the teeth grow continuously throughout life, as opposed to the finite growth process that is observed in brachydont species. Hypsodont teeth that grow continuously in this way are called hypselodont (or, simply, elodont). The.

Humans and many animals have a monogastric digestive system as illustrated in Figure 6.5.5 6.5. 5. The process of digestion begins with the mouth and the intake of food. The teeth play an important role in masticating (chewing) or physically breaking down food into smaller particles.
