Nitrogen is essential for protein and compound synthesis in autotrophs, and it is acquired from the soil either as inorganic nitrates/nitrites or as organic compounds prepared by bacteria from atmospheric nitrogen.

Nitrogen plays a crucial role in autotrophs, serving as an essential element for the synthesis of proteins and other vital compounds. Autotrophs acquire nitrogen from the soil in the form of inorganic nitrates or nitrites. Alternatively, some autotrophs obtain nitrogen in the form of organic compounds that have been prepared by nitrogen-fixing bacteria from atmospheric nitrogen. This process allows autotrophs to incorporate nitrogen into their cellular structures, supporting the formation of proteins, nucleic acids, and other essential molecules necessary for their growth, development, and overall metabolic functions. Nitrogen acquisition is pivotal for the proper functioning and health of autotrophic organisms.
