Nitrogen fixation is the process of converting atmospheric nitrogen (N2) into a form that can be used by living organisms, such as ammonia (NH3) or nitrate (NO3-). This process is essential for the growth and survival of plants and other organisms.
Some bacteria, cyanobacteria and legumes fix nitrogen:
1. Bacteria: Some free-living bacteria such as Azotobacter, Clostridium, and Klebsiella can fix nitrogen. These bacteria are found in soil, water, and on plant surfaces.
2. Cyanobacteria: These are photosynthetic bacteria that can fix nitrogen. They are found in aquatic environments such as oceans, lakes, and ponds.
3. Legumes: Legumes are a type of plant that have a symbiotic relationship with nitrogen-fixing bacteria called rhizobia. These bacteria live in nodules on the roots of the plant and fix nitrogen for the plant to use.
Therefore, option C is the correct answer as nitrogen fixation occurs in some bacteria, cyanobacteria, and legumes.
