Living organisms require nitrogen to make nitrates and nitrites, which are essential components for building proteins, nucleic acids, and other important biomolecules. These compounds are necessary for growth, development, and overall cellular function in organisms.
Living organisms require nitrogen to make nitrates and nitrites, which are used to build proteins and nucleic acids like DNA and RNA. Nitrogen is an essential component of these macromolecules, which are crucial for the growth and functioning of cells in living organisms.
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
The main ones are proteins and nucleic acids.

Nitrogen must be cycled through an ecosystem so that the nitrogen is available for organisms to make proteins.
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.
Nitrogen is needed for everything to grow well. It is essentially a building block for proteins. Generally, nitrogen makes things grow more. For plants they make things grow more and become greener. Nitrogen is added to soil using fertilizer, or nitrogen-fixing plants.
Nitrogen is consumed by different organisms in different ways. Legumes (a type of plant) are able to take nitrogen straight out of the atmosphere (which is roughly 78% nitrogen gas). Animals aren't able to do this so they must obtain their nitrogen by eating substances such as vegetables and meat. We break down proteins (largely from meat) down to their constituents which are amino acids. This is how we obtain our source of nitrogen (amino acids contain nitrogen atoms). We then use these amino acids to build proteins that we need in our body such as tissue, enzymes, antibodies and more.
Organisms would not be able to get the nutrients they need to make proteins.
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.
