Question

How the bacteria present in soil and
root nodules of leguminous plant care
useful?​

Answer 1

Answer:

These bacteria supply nitrates and nitrites and amino acids to the plants. They have the capacity to convert nitrogen in the soil and air to form such compounds. ... Which is useful for the growth or development of the leguminous plants.

Answer 2

Answer:

The leguminous plants have root nodules in which the bacteria. Rhizobium resides symbiotically with the plants such as peas, beans, soya beans, etc. These bacteria supply nitrates and nitrites and amino acids to the plants. They have capacity to convert nitrogen in the soil and air to form such compounds. This is called bacterial nitrogen fixation. In return the plants provide energy in the form of carbohydrates and the place to stay in the root nodules to the bacteria. Some more bacteria and blue green algae such as Anabaena, Nostoc and Azotobacter, are free living in the soil, they too perform similar function of nitrogen fixation. Both types of bacteria make the soil fertile and reduce the demand of chemical fertilizers.
