Ruminant animals like cows possess a unique digestive system that helps them digest cellulose. Which of these is a characteristic feature of ruminant digestion?
Options
They have a single stomach chamber where digestion occurs.
They quickly swallow food and store it in a part of their stomach called the rumen.
They lack a food pipe, and food directly enters the stomach.
They digest food primarily through enzymatic action in their large intestine.
Explanation
Ruminants are herbivorous animals with a specialized four-chambered stomach. They quickly swallow grass without chewing much, storing it in the rumen, the first chamber. Later, this partially digested food, called cud, is regurgitated to the mouth for thorough chewing (rumination). This process helps break down tough cellulose, which is difficult to digest. Options 1, 3, and 4 describe features not characteristic of ruminant digestion.
