Detailed explanation-1: -Once nitrogen is converted into compounds like ammonium and nitrate, these can be taken up from soils by plants and then the nitrogen can be used to form macromolecules like proteins and nucleic acids (DNA and RNA). Nitrogen is a crucially important component for all life.

Detailed explanation-2: -Nitrogen is one of the primary nutrients critical for the survival of all living organisms. It is a necessary component of many biomolecules, including proteins, DNA, and chlorophyll.

Detailed explanation-3: -Nitrogen is a key element in the nucleic acids DNA and RNA, which are the most important of all biological molecules and crucial for all living things. DNA carries the genetic information, which means the instructions for how to make up a life form.

Detailed explanation-4: -All living things need nitrogen to build proteins and other important body chemicals. However, most organisms, including plants, animals and fungi, cannot get the nitrogen they need from the atmospheric supply.

Detailed explanation-5: -Tell how we get the nitrogen we need to make proteins and DNA if we can’t get it from breathing. We don’t have the enzymes necessary to remove nitrogen from the atmosphere; we get our nitrogen from the FOOD WE EAT.
