Question

What is nitrogen fixation? And why plants need to fix nitrogen?​

Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development.

Example:

ribosomes

Cyno Bacteria. etc...

Answer 2

$<marque>$

The chemical processes by which atmospheric nitrogen is assimilated into organic compounds, especially by certain microorganisms as part of the nitrogen cycle is called as Nitrogen Fixation.

The plant provides sugars from photosynthesis that are utilized by the nitrogen-fixing microorganism for the energy it needs for nitrogen fixation. In exchange for these carbon sources, the microbe provides fixed nitrogen to the host plant for its growth.
