The main ones are proteins and nucleic acids.
Nitrogen fixation
Living things that need nitrogen to make complex nitrogen compounds are called nitrogen-fixing organisms. These organisms have the ability to convert atmospheric nitrogen gas (N2) into usable forms such as ammonia or nitrates, which can be incorporated into various biological molecules. Examples of nitrogen-fixing organisms include certain bacteria and some plants, such as legumes.
Higher organisms use nitrogen to make proteins, nucleic acids (DNA and RNA), and other essential molecules necessary for growth and function. Nitrogen is a crucial component of amino acids, which are the building blocks of proteins, and is required for various biological processes within the body.
Carbon, hydrogen, nitrogen and oxygen
All organisms need nitrogen because it is a component of all proteins and many other essential molecules.
All organisms need nitrogen because it is a component of all proteins and many other essential molecules.
Nitrogen is a vital component of many biological molecules, including proteins and nucleic acids. It is essential for processes like growth, reproduction, and DNA synthesis in organisms. Plants, animals, and microorganisms all require nitrogen to build and maintain their cellular structures and perform various metabolic functions.
Nitrogen
Nitrogen is an element, and two nitrogen atoms make up a nitrogen molecule.
Carbon Oxygen Hydrogen Nitrogen
The four major elements found in organisms are carbon, hydrogen, oxygen, and nitrogen. These elements make up the majority of biological molecules, such as carbohydrates, lipids, proteins, and nucleic acids, which are essential for life.
Six: hydrogen, carbon, oxygen, nitrogen, phosphorus and sulfur.
