nitrogen
Most organisms are unable to make nitrogen directly from the atmosphere. Instead, they rely on nitrogen-fixing bacteria to convert atmospheric nitrogen into a form that can be used by plants and other organisms for essential functions like protein synthesis.
The two most common elements in Earth's atmosphere are nitrogen, making up about 78%, and oxygen, making up about 21%.
nitrogen takes up 78% in volume and 75% in weight
The two most abundant elements in Earth's atmosphere are nitrogen and oxygen. Nitrogen makes up about 78% of the atmosphere, while oxygen is around 21%. Both of these elements are essential for supporting life on Earth.
These gases are nitrogen, oxygen and argon.
Nitrogen.
Most organisms are unable to make nitrogen directly from the atmosphere. Instead, they rely on nitrogen-fixing bacteria to convert atmospheric nitrogen into a form that can be used by plants and other organisms for essential functions like protein synthesis.
Most organisms are able to take oxygen from the atmosphere through respiration. Plants are able to take in carbon dioxide from the atmosphere during photosynthesis.
The nitrogen is about 78% in air but living organisms can not take from air.
Ganymede, a moon of Jupiter, lacks a significant atmosphere. Without an atmosphere to provide oxygen for respiration, humans and most living organisms would be unable to breathe on Ganymede.
The most important elements in the Earth's atmosphere are N (nitrogen) and O (oxygen).

Potassium is not typically found in significant amounts in Earth's atmosphere. It is one of the most abundant elements on Earth and is primarily found in minerals in the Earth's crust, as well as in seawater and living organisms.
These elements are nitrogen, oxygen and argon.
