Science — AI-generated practice question

Herbivores eat grass and plant material, which contains cellulose — a complex carbohydrate that is difficult to digest and requires more time and a longer digestive tract to break down completely. Meat (eaten by carnivores) is easier to digest, so carnivores like tigers have a shorter small intestine.

• The textbook directly states this fact: "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 2 marks, examiners expect two points: (1) herbivores need to digest cellulose → longer intestine, and (2) meat is easier to digest → carnivores have shorter intestine.
• Always mention cellulose by name — it is the key term that earns marks.
