Answer
Longer small intestine
Reason — Herbivores have a longer small intestine because their diet consists mainly of plant material rich in cellulose, which is difficult to digest.
The increased length allows more time and surface area for digestion and absorption which also provides space for symbiotic bacteria that help break down cellulose into simpler, absorbable substances, enabling herbivores to extract maximum nutrients from their plant-based food.
