2. Grass containing cellulose is easier to digest
3. Herbivores do not eat meat
4. No specific reason

Answer 1

Correct Answer - Option 1 : Grass containing cellulose is harder to digest

The correct answer is Grass containing cellulose is harder to digest.

Concept:

• Digestion: The process of conversion of complex food substances to simple absorbable forms is called digestion and is carried out by our digestive system by mechanical and biochemical methods
• The digestion is performed in the following manner
• Mouth – Oesophagus – Stomach – Small intestine – Large intestine

Explanation:

• The food from the stomach enters the small intestine. This is the longest part of the alimentary canal which is fitted into a compact space because of extensive coiling. The length of the small intestine differs in various animals depending on the food they eat.
• Herbivores eating grass need a longer small intestine to allow the cellulose to be digested as it is harder to digest
• Meat is easier to digest, hence carnivores like tigers have a shorter small intestine.

• The small intestine is the site of the complete digestion of carbohydrates, proteins and fats. It receives the secretions of the liver and pancreas for this purpose.
