Final answer:
A giraffe's digestion process involves swallowing leaves without chewing, allowing for better digestion. The digestion process can take several hours.
Step-by-step explanation:
The time it takes for a giraffe's food to reach its stomach can vary depending on the type of food. When a giraffe eats leaves, it first swallows them without chewing, and the leaves go directly to its 'second stomach' or reticulum. Later, the giraffe regurgitates the food, chews it properly, and swallows it again. This process helps break down the tough leaves and allows for better digestion. Overall, the entire digestion process in a giraffe can take several hours.
