Oxygen + Nitrogen: Essential for animal and micro-organic processes.
Carbon Dioxide: Essential to plant respiration.
Argon: Pretty passive and no doubt least essential to life.
there is some sulphuric acid and carbon dioxide with very little water vapor
Venus' atmosphere is primarily composed of carbon dioxide (96.5%) with traces of nitrogen and sulfur dioxide.
It not being certain of what amount or percentage is considered a "major" or "minor" gas, I have chosen to give the list of known gases in significant quantities: Hydrogen gas- 83% Helium gas- 15% Methane gas- 2%
Nitrogen. This is "minor".Carbon dioxide. This is the "major" gas. It makes up about 95% of the atmosphere.
The major gases in Neptune's atmosphere are hydrogen, helium, and methane. Hydrogen and helium are the most abundant gases, with methane making up a smaller but still significant proportion.
Hydrogen,and Helium
Neptune's minor atmospheric gases are ethane and hydrogen deuteride. Its major gases are hydrogen, helium, and methane. Neptune's blue appearance is caused by the mixture of these gases.

No, carbon dioxide is not considered a trace gas in Earth's atmosphere. Trace gases are typically present in very small concentrations compared to major atmospheric gases like nitrogen and oxygen. Carbon dioxide, while not a trace gas, is an important greenhouse gas that plays a key role in regulating Earth's climate.
hhhhhhhhhhhhhhiiiiiiiiiiiiiiiiiiiiiiiiii the major gases are h2o n co2 thanks byeeeeeeeeee
It never was - Nitrogen is the "major gas".

Carbon dioxide is the major greenhouse gas, though methane and other gases are also important.
