Solution

Reasoning out: 2 Marks


During a physical activity we need more energy. Whenever a person needs extra energy he/she breathes faster. As a result, more oxygen is supplied to our cells. It speeds up the breakdown of food and more and more  energy is released. Due to rapid this  breakdown of food we feel hungry.
