it is a symbiotic relationship
legumes
change nitrogen gas into ammonia
"symbiotic"
Legumes have a symbiotic relationship with certain bacteria called rhizobia. These bacteria live in nodules on the roots of legumes and convert atmospheric nitrogen into a form that the plant can use for growth. This process is called nitrogen fixation and helps enrich the soil with nutrients.
They are called nitryfying bacteria. Examples are Rhizobium, Anabena etc
Bacteria in the soil called nitrogen-fixing bacteria go through a process called nitrogen-fixation which allows nitrogen to enter the atmosphere
is called Nitrogen-fixing bacteria
Special class of bacteria called Rhizomes live on the roots of leguminus plants. They take free nitrate and nitrites from the environment and change to a form that can be readily used by plants. Relationship between nitrogen fixing bacteria and plants is called Symbiosis.
Legume plants have a symbiotic relationship with nitrogen-fixing bacteria called rhizobia. These bacteria convert atmospheric nitrogen into a form that the plants can use for growth, which benefits both the plant and the bacteria. Examples of legume plants include peas, beans, and clover.
The process you have mentioned is called nitrogen fixation. It is done by bacteria named Rhizobium Bacillus.
