The most abundant element in the Earth’s atmosphere and is a constituent of all living matter is Nitrogen.

• In the constituent of gases, Nitrogen makes up 78% whereas Oxygen makes up to 21% and other gases come in the 1%.

• Nitrogen is odorless and colorless. It is present in the air, soil, and even in the water we consume.

• In plants, Nitrogen acts as an essential element that helps their growth. Without Nitrogen, plants can face decreased growth and even yellow coloring of leaves. But excess or too much Nitrogen can lead to harm to the environment. This also makes Nitrogen an essential element for humans to consume.

• Nitrogen is also present in living beings through nucleic acids such as DNA and RNA which help as a genetic material or protein synthesis.
• That's why Nitrogen is known to be the most abundant as well a constituent of all living matter.
