Which of the following activities are involved in the process of rumination? I. Re-chewing II Regurgitation III, Vomiting

Answer Details

Rumination is a process of digestion that occurs in ruminant animals like cattle, sheep, and goats. During rumination, the animal regurgitates and re-chews partially digested food, which is also called cud. This process helps to break down the plant matter more thoroughly and extract more nutrients. Vomiting is not part of the process of rumination because it involves the expulsion of undigested food from the stomach, rather than the re-chewing of partially digested food. Therefore, the correct answer is (a) I and II only.
