Science (086) — AI-generated practice question

Herbivores have a longer small intestine than carnivores.

Herbivores eat grass and plant material, which contains cellulose. Cellulose is difficult to digest and requires more time and a greater length of intestine for complete digestion. Carnivores eat meat, which is easier to digest, so a shorter small intestine is sufficient for complete digestion.

For example, tigers (carnivores) have a shorter small intestine, while grass-eating animals (herbivores) have a longer one.

• The key fact is directly stated in the textbook: "Herbivores eating grass need a longer small intestine to allow the cellulose to be digested. Meat is easier to digest, hence carnivores like tigers have a shorter small intestine."
• For 3 marks, examiners expect: (1) the difference stated clearly, (2) reason for herbivores' longer intestine (cellulose is hard to digest), and (3) reason for carnivores' shorter intestine (meat is easier to digest). Give an example if possible.
• Avoid writing lengthy paragraphs — three crisp points are enough.
