because these 4 elements that are listed are the most common elements on planet earth. most percentage of the eart is made of there 4 elements but not all some elments like iron are also there but a extremly small percentage
These elements are nitrogen, oxygen and argon.
Carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and phosphorous (P) are the main elements. Other important "players" are sulfur (S), sodium (Na), calcium (Ca), and magnesium (Mg).
These elements are oxygen and nitrogen.
99% of the atmosphere is nitrogen (78%) and oxygen (21%).
Assuming you meant the acronym CHNOPS. It stands for carbon, hydrogen, nitrogen, oxygen, phosphorus & sulphur - the six most important chemical elements that make up most biological elements found on Earth.
The most important elements in the Earth's atmosphere are N (nitrogen) and O (oxygen).
hydrogen becuase it gives us all water by combining with oxygen (h20) nitrogen cause.............
These elements are nitrogen, oxygen and argon.
The two dominant elements in Earth's atmosphere are nitrogen and oxygen. Nitrogen makes up about 78% of the atmosphere, while oxygen accounts for about 21%.
Carbon, hydrogen, oxygen, and nitrogen are important for sustaining life on Earth because they are essential elements found in all living organisms. Carbon is the building block of organic molecules, hydrogen and oxygen are crucial for energy production and cellular processes, and nitrogen is necessary for the formation of proteins and DNA. These elements play key roles in the structure and function of living organisms, making them vital for life as we know it.
Carbon, hydrogen, oxygen, and nitrogen are important to life on Earth because they are the building blocks of all living organisms. These elements are essential for the formation of molecules like proteins, carbohydrates, fats, and nucleic acids, which are crucial for the functioning and survival of living organisms. Additionally, these elements are involved in various biological processes such as respiration, photosynthesis, and DNA replication.
Carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and phosphorous (P) are the main elements. Other important "players" are sulfur (S), sodium (Na), calcium (Ca), and magnesium (Mg).
Nitrogen 78 % Silica in soil
