Question

Choose the correct order of terms that describes the process of nutrition in ruminants:

• A. Swallowing → partial digestion → chewing of cud → complete digestion
• B. Chewing of cud → swallowing → partial digestion → complete digestion
• C. Chewing of cud → swallowing → mixing with digestive juices → digestion
• D. Urinary bladder → kidney → ureter → urethra

Answer 1

The correct option is A

Swallowing → partial digestion → chewing of cud → complete digestion

The correct option is A.

Explanation of the correct option:

1. In ruminants, the process of digestion starts with the chewing and swallowing of food.
2. When ruminants feed, they only consume or gulp as much of the food as they can before swallowing it.
3. This is essentially an adaptation that these animals have developed to consume food as quickly as possible in order to avoid being hunted by any predators while doing so.
4. In ruminants, the digestive process goes as follows: swallowing, partial digestion (cud), cud brought back to mouth, chewing of the cud, other stomach compartments, small intestine, and complete digestion.

Final Answer: - Hence the correct sequence is Swallowing → partial digestion → chewing of cud → complete digestion.
