Detailed explanation-1: -Mouth. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
Detailed explanation-2: -Obtaining nutrition and energy from food is a multi-step process. For true animals, the first step is ingestion, the act of taking in food. This is followed by digestion, absorption, and elimination.
Detailed explanation-3: -Respiration is the process by which the glucose in the food is broken down in the presence of oxygen to produce energy. This energy is utilised by our body for its survival.
