Delicate balance of \(CO_2\) and \(O_2\) is not disturbed by:
- Deforestation
- Respiration
- Burning of coal
- Burning of petroleum
The Correct Option is B
Solution and Explanation
The equilibrium between carbon dioxide (CO$_2$) and oxygen (O$_2$) in the atmosphere is primarily regulated by the process of photosynthesis in plants, which absorbs CO$_2$ and releases O$_2$. Conversely, respiration by both plants and animals releases CO$_2$ and consumes O$_2$.
Step 2: Identifying the correct process
While activities such as coal burning, deforestation, and petroleum combustion disrupt the delicate balance of CO$_2$ and O$_2$, respiration does not. Respiration is a natural process where the consumption of O$_2$ and the release of CO$_2$ are in balance, ensuring that atmospheric levels remain stable.
Therefore, respiration does not disturb the delicate balance.

Concepts Used:
Oxygen
Oxygen is an important element in the combustion process. It is a member of the chalcogen group on the periodic table which is one of the most abundant elements in the Earth’s crust.
Oxygen is very important for a living organism to survive, multiply, and for converting food into energy. It is the only living gas for human beings and they inhale it from their nose reaching to their lungs.
Only oxygen gas gives our cells the ability to convert food into energy which is very important for us to survive.
Oxygen is a chemical compound with the symbol O and atomic number 8.
Properties of Oxygen:
- Oxygen gas is odorless, colorless and insipid in a normal state. Liquid oxygen is slightly paramagnetic. It is reactive and forms oxides with every element except helium, neon, krypton, and argon. It is moderately soluble in water.
- It is one of the common allotropes of oxygen.
- Trioxygen is the most reactive allotrope of oxygen that would cause damage to lung tissue. This allotrope is termed as ozone.
