The delicate balance of

CO_{2}

and

O_{2}

is NOT disturbed by:

(A)Burning of Coal
(B)Deforestation
(C)Burning of petroleum
(D)Respiration✓ Correct

Answer: (D)

Solution

Respiration is a natural biological process that is part of the carbon-oxygen cycle. The

CO_{2}

released during respiration is balanced by the

O_{2}

produced during photosynthesis, maintaining equilibrium. In contrast, burning of fossil fuels (coal, petroleum) and deforestation are anthropogenic activities that disturb this natural balance by adding excess

CO_{2}

without corresponding

O_{2}

production.
