Answer 1

Approximately 78% of Earth's atmosphere is composed of nitrogen gas (N2).

Key Points

Nitrogen is the most abundant gas in the atmosphere, followed by oxygen, which makes up about 21%.
The remaining 1% consists of various trace gases, including argon, carbon dioxide, neon, helium, methane, krypton, hydrogen, xenon, ozone, and others.
Nitrogen's presence in the atmosphere is crucial for various biological and ecological processes
Atmospheric Nitrogen is useful in Nitrogen Fixation, Plant Growth, Human and Animal Nutrition, Nitrogen Cycle and Fertilizer Production
While atmospheric nitrogen is inert and doesn't readily participate in biological processes, its conversion into more reactive forms by nitrogen-fixing bacteria is crucial for sustaining life on Earth. The nitrogen cycle plays a vital role in maintaining the balance of nitrogen in ecosystems.
