Human gets energy from food molecules through the process of cellular respiration.
Explanation:
Digestion of food into simpler nutrients is carried out by digestive system. These nutrients are absorbed by blood and are carried to the cells. Cellular respiration is the process of oxidation of nutrients and release of energy stored in them. The released energy is stored in form of ATP. Hence, the process of cellular respiration retrieves energy from food and stored it into the chemical bonds of ATP.
The food we eat contains energy. This energy is taken by us through eating food. It is a natural process that all living things eat food to get energy for their living. The energy in the food is transferred to the bodies of the living things which in turns provide them energy.
When humans eat the food, the food is broken down in the human body through a process of digestion. This process breaks down food into small particles, releasing energy from them and providing it to the body, The food molecules release energy and the process of digestion takes these molecules , breaks them down, extract the energy and give it to human body. So this is how a human body gets energy from eating food
