Energy is made from oxygen and glucose, when reacted together. Oxygen enters the body via the respiratory system and glucose enters through the digestive system. These two systems link as they both provide the formulae for energy. When glucose and oxygen are both in the body, the cardiovascular transports it via blood to the place in which it is needed in the body, for example the muscles. This is also links with the digestive and respiratory system as it provides the transportation of the energy.

It’s very simple ok hope you have confidence

Nutrients provide the energy and raw materials that the human body needs.
Digestion is the breaking down of foods so that it can be absorbed and provide nutrients. Synthesis occurs when the body manufactures some thing that it needs from the raw materials that it obtains through digestion.

No. The body's fat is a reserve of energy, and is only tapped into (used) when the body runs out of, and needs, calories from normal food digestion processes to produce energy. To lose fat, your body needs exercise.
Yes, food provides the body with the energy it needs to be active.
The smallest contributor to our energy needs is usually renewable sources such as solar, wind, and hydroelectric power. These sources often provide a smaller percentage of overall energy consumption compared to fossil fuels and other non-renewable sources. However, their importance is increasing as efforts to transition to cleaner and more sustainable energy systems continue to grow.
Carbohydrates are essential to provide energy for the body because they are quickest source of the energy for the body. They meet the body's immediate energy needs and are the first source of the energy the body uses.
