what are nitrogen fixing bacteria
Answer ( 1 )
Nitrogen-fixing bacteria are a group of microorganisms that play a crucial role in the nitrogen cycle, a fundamental process in nature. These bacteria have the remarkable ability to convert atmospheric nitrogen gas (N2) into a form of nitrogen that plants can use, typically ammonia (NH3) or nitrate (NO3-). This process, known as nitrogen fixation, provides an essential source of nitrogen for plant growth and ultimately sustains the entire ecosystem. Some well-known examples of nitrogen-fixing bacteria include species of Rhizobium, Azotobacter, and Clostridium. Through their symbiotic relationships with plants or by living freely in the soil, these bacteria contribute significantly to agricultural productivity and environmental sustainability.
