Answer:
- All living organism requires energy to live and to perform any useful functions.
- This energy they get from food they eat. Energy is released when food contains nutrients, let’s say carbohydrate (glucose).
- Energy released in the cells when oxidation of glucose occurs which means the carbohydrates which we eat converted into simpler substances with the help of oxygen.
- For complete oxidation of glucose (i.e the breakdown into simpler substances) oxygen is necessary.
