Question
Nitrogen is converted before it can be utilized by plants. This process is known as
- Nitrification
- Denitrification
- Nitrogen fixation
- Immobilization
Hint:
Rhizobium is responsible for this process.
The correct answer is: Nitrogen fixation
- Nitrogen is important for the normal growth and metabolism of plants
- Nitrogen deficiency can be observed as chlorosis in plants
- Atmospheric nitrogen cannot be utilized by plants as such
- Nitrogen is converted into its derivatives by a process called nitrogen fixation
- In leguminous plants, nitrogen fixation occurs through a bacteria called rhizobium which is present in the form of nodules in the roots of the plants
