Explain by writing a word equation.
Respiration is a chemical change.
Chemical change is a process in which a new substance is formed.
- Respiration is irreversible process
- During respiration, oxygen is convert into carbon-dioxide( a new substance is formed).
- During respiration, there is change in their chemical composition.
- During respiration, absorption and evolution of energy takes place.
These are characteristics of chemical reaction. Hence, respiration is a chemical reaction.
