Although invisible, air is one of the most vital components of our environment. The Composition of Air Air is made up of several gases, each serving specific purposes. The primary components of air include: Nitrogen (78%) : The most abundant gas, nitrogen plays a crucial role in plant growth through the nitrogen cycle. Oxygen (21%) : Essential for respiration in humans, animals, and most living organisms. Argon (0.93%) : An inert gas that has minimal effect on the environment. Carbon Dioxide (0.04%) : Vital for photosynthesis in plants, though excessive amounts contribute to global warming. Other Gases : Trace amounts of gases like neon, helium, methane, and ozone are also present. The Role of Air in Life Air is indispensable for life on Earth. Its functions include: Supporting Br...
