The air is about 80% nitrogen- but cannot be used by plants for food. Nitrogen fixing bacteria transform nitrogen in the air to nitrogen in the soil that plants CAN use- resulting in greatly improved plant growth, and more fertile soil.
nitrogen fixation
Yes.
because it is in the food you eat.
The role of bacteria in the Nitrogen Cycle is to perform biological nitrogen fixation. This process is an important part of the Nitrogen Cycle because it converts oxygen into ammonia that plants are then able to use.

Decomposing bacteria and nitrogen-converting bacteria important to farmers because they help to send nutrients through the soil. These types of bacteria regulate nitrogen n the soil.
why are nitrogen fixing bacteria so important to other organism
bacteria in root fixes free nitrogen ito simple compounds
nitrogen moves through living and non-living ecosystems
nitrogen fixation
Nitrification, an important step in the nitrogen cycle.
Nitrogen needs to be fixed before it is used by plants.
Yes.
Rhizobium Bacillus is the bacteria that converts nitrogen gas in the air into ammonia. It plays an important role the nitrogen cycle by fixing nitrogen which is otherwise an inert gas.
Although the air is made up of about 80% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle
because it is in the food you eat.
