Question 6
What is the Nitrogen Cycle? What is nitrogen fixation ?
Answer
The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms in the environment, including in the atmosphere, soil, and living organisms.
Nitrogen fixation is the process by which atmospheric nitrogen gas is converted into a usable form, such as ammonia or nitrate, by certain bacteria, including symbiotic bacteria found in the roots of leguminous plants. This process is essential for making nitrogen available for use by plants and other organisms.
