the body that needs exercise are the muscles in our body and our bones
the basics of weight gain is eating more than what you need so that the excess can be stored to gain weight and physical exercise which will demand the body to add more muscle so that the weight gained is healthy and not fat

This type of exercise, during which the body's oxygen need exceeds the lungs' ability to replenish it is called anaerobic exercise -- literally, 'without air.' Exertion of longer duration, during which the body is able to sustain the energy output (and the lungs have the capacity to provide the necessary oxygen for a longer period of time) is known as aerobic exercise.
Because the demand for oxygen and glucose increases, and the heart and lungs need to speed up to keep up with the demand.
you need to exercise because it keeps your body fit and healthy with good shape
No, because what little you do eat, your body doesn't know how to sort it out and especially if your an athlete, you need to eat more for your body to turn it into protein, if you exercise anyway it wouldn't make you gain fat it would give you more strength and energy. You need more food, healthy food, to support your body when doing physical activities. If that makes sense.
Hunger is the body's perceptual response to undernourishment (the need for nutrients).
Physical education is basically the education of exercise practiced in education centres as it is important for the need of human body for it to become healthy and strong. We understand that Physical education is guided to stay fit, healthy and strong one must learn physical education in order to evolve.
