Final answer:
The question is about characters from the novel 'Life of Pi' and their bodily functions while stranded at sea. The frequency of their bowel movements would be irregular due to their extreme circumstances, though such details are not a focus in the novel.
Step-by-step explanation:
The question 'How often do Pi and Richard Parker have a bowel movement?' refers to the characters from Yann Martel's novel Life of Pi. This question relates to the health and bodily functions of the two castaways, a young boy named Pi and a Bengal tiger named Richard Parker, who are stranded together on a lifeboat in the Pacific Ocean. It's worth noting that the frequency of bowel movements can depend on several factors including diet, hydration, and stress levels. In the context of survival at sea, the fictional characters' bowel movement frequency would likely be irregular due to limited food and water intake, and high stress conditions. However, the novel does not discuss these details extensively.
