DIGESTION IN ANIMALS:

• Different organisms have different organizations of the digestive system based on their food habits.

Herbivores animals

• The Digestive system is adapted to feed on plant materials.
• The digestion is aided by the presence of mutualistic gut flora such as cellulase enzyme.
• They have a longer small intestine for the digestion of cellulose in the food.

• The cellulose digestion takes a longer time than usual food so possesses specialized dentition along with a long digestive system.

Carnivores animals

• Dentition to hunt and kill the other animals.
• Unlike herbivores, these animals possess smaller small intestines.
• Digestion of proteins does not require a complex digestion mechanism.
