Answer:
Respiration – The energy required by our body to stay active is provided by the food which we eat. During digestion, food particles are broken down into simpler substances. For example, wheat, rice, potatoes etc all contain carbohydrates. These carbohydrates are broken down into simpler substances called glucose. The glucose on combustion with oxygen gives CO2 gas, H2O and evolves heat. This reaction is called Respiration.
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
