what is nitrogen fixation class 8

Nitrogen fixation is a crucial biological process that converts atmospheric nitrogen into ammonia, which can be utilized by organisms, particularly plants and other microbes. This process is essential for the nitrogen cycle and is primarily carried out by certain bacterial species like Rhizobium, Azotobacter, and others, as well as by natural phenomena such as lightning and ultraviolet rays. Nitrogen fixation is important because nitrogen is a vital but limiting element for all organisms, including humans, plants, and other organisms, as it is a key component of proteins and other cellular compounds. This process is significant for making nitrogen available in a form that plants can use to grow, and it plays a crucial role in maintaining the balance of nitrogen in the environment.
