Detailed explanation-3: -There are four stages involved in the process of deriving nutrients and energy from the food eaten. Ingestion, often known as bringing food into the system, is the initial step in the digestive process for animals that chew their food, followed by the stages of digestion, absorption, and finally, elimination.
