what are nitrogen fixing bacteria in short
Answers
Answer:
Rhizobium bacteria is an example.
Nitrogen-fixing bacteria are prokaryotic microorganisms that are capable of transforming nitrogen gas from the atmosphere into “fixed nitrogen” compounds, such as ammonia, that are usable by plants.

Nitrogen is a component of proteins and nucleic acids and is essential to life on Earth.
Although nitrogen is abundant in the atmosphere, most organisms cannot use it in that form.
Nitrogen-fixing bacteria accomplish more than 90 percent of all nitrogen fixation and thus play an important role in the nitrogen cycle.
Because of these bacteria, legumes have the nitrogen necessary to make lots of proteins, which, in turn, is why beans are such a good source of dietary protein for humans and other animals.
Additionally, legumes and certain cereal grasses are often grown as green manures and for crop rotation on farms as an organic source of nitrogen for other crops.

HELLO !!!!
Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.
EXAMPLE;
- Azotobacter
- Archaea.
