How is the length of intestine related to food habit of the animal?

Answer 1

Exclusive carnivores have the shortest intestines, because meat is easier to digest (starting in the stomach) and it's preferable that it leaves the body quickly. Meat rots as vegetable doesn't.

Exclusive herbivores, on the other hand, have the longest intestines. They have symbiotic organisms living in them which produce the enzyme necessary to digest the plant cell's outer wall, made of cellulose, without which the cell will pass through intact if not broken in another way, mechanically. Because of this, since vegetable wasts pose less health risks if rotting, it's preferable that it stays in the gut for a long time, being digested by the enzyme we don't produce.

Omnivores are in between.

Answer 2

The length of an animal's intestine is often correlated with its diet. Animals that consume plant material typically have longer intestines to aid in the digestion of complex fibers, while carnivorous animals may have shorter intestines as meat is easier to digest. The length of the intestine helps optimize nutrient absorption based on the type of food the animal consumes.
