Hint: You can start by explaining how humans get energy for their daily work. Then discuss how food is the most important requirement for our body to fulfill the need for muscular energy in our daily work.
Complete step-by-step answer:
We as humans get all the energy required to do our daily tasks from the food we consume. Humans eat food like vegetables or meat. The animals that we eat have taken nourishment directly or indirectly from plants. So, even if we eat meat we are taking energy from plants. So plants are the primary producer of food. Plants produce their food with the help of sunlight, in a process called photosynthesis they use inorganic substances, and with the help of sunlight convert them to glucose. Glucose now can act as a source of energy when needed. This glucose is transferred to our body when we consume food. This glucose is then used up in our muscular, neural, and other activities.
So, the muscular energy required by our body is given to us by the food we consume.
In our muscles, by metabolic reactions, the energy stored in the glucose molecules is released alongside the breakdown of the glucose molecule. Many other compounds aside from glucose that are present in our diet also provide us with energy.
Note: In the solution above we mentioned that the muscular energy required by our body is given to us by the food we consume. But oxygen also plays an important role in the process. Glucose provides us with energy when it reacts with oxygen in our body, but it was not the correct option as carbon dioxide can also work in place of oxygen.
