ANSWER
Respiration is a chemical change as new substances like carbon dioxide and water are formed. Also there is change in the mass as glucose is oxidised by oxygen and heat is released. This change is permanent. The food we eat includes fats, vitamims, proteins , etc.
.During digestion carbohydrates are broke down into simpler substance calles glucose.
Glucose combines with oxygen in the cell of our body to form carbon dioxide and water along with energy.T his reaction is called respiration.
Since energy is released in this process hence respiration is an exothermic process.
