Why is the mixed form of atmospheric gases necessary for life?
Answer and explanation
Correct answer: Because one gas alone cannot perform all biological and thermal functions
The atmosphere is useful because its gases perform complementary functions. Oxygen supports respiration and combustion, carbon dioxide is used in photosynthesis and contributes to heat retention, nitrogen is essential for building proteins after biological fixation, and water vapour drives clouds and rainfall. No single gas can provide all these services. Therefore, the balanced mixture supports organisms, weather processes and a suitable surface temperature, making option A correct.
