what are nitrogen fixers?

Question

Accepted Answer

Nitrogen fixers are organisms that convert atmospheric nitrogen into a usable form for plants and other organisms.

Nitrogen fixers play a crucial role in the nitrogen cycle by converting atmospheric nitrogen gas (N2) into ammonia (NH3) or nitrate (NO3-).
These organisms have the ability to break the strong triple bond between nitrogen atoms and convert it into a form that can be utilized by plants.
Examples of nitrogen fixers include certain bacteria, such as Rhizobium, Azotobacter, and Frankia, as well as some cyanobacteria and archaea.
Leguminous plants, such as soybeans, peas, and clover, form symbiotic relationships with nitrogen-fixing bacteria in their root nodules.
Nitrogen fixation is an essential process for maintaining soil fertility and ensuring the availability of nitrogen for plant growth.
