Question
How does digestion occur in ruminants grass-eating animals?
✓
Answer
Ruminants quickly swallow the grass and store it in a separate part of the stomach called rumen. Here the food gets partially digested and is called cud. Later the cud returns to the mouth in small lumps and the animal chews it. This process is called rumination. The cellulose present in grass is digested here by the action of certain bacteria which are not present in humans.
