Nitrogen
Nitrogen is an element that can be fixed into plant material by bacteria. Certain bacteria, like rhizobia and cyanobacteria, have the ability to convert atmospheric nitrogen into a form that plants can use, which helps in the fertilization and growth of plants.
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.
OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants. fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.
To kill bacteria.
Bacterial smears are fixed before staining to adhere the bacteria to the slide and kill the bacteria, which helps to prevent them from washing away during the staining process. Additionally, fixing the bacteria helps to preserve their cellular structures and prevent distortion during staining.

Nitrogen fixation is the process by which certain bacteria convert atmospheric nitrogen into a usable form for plants, such as ammonium or nitrate. This can occur through the activity of symbiotic relationships with leguminous plants, free-living soil bacteria, or industrial processes.

No. Chlorine is a chemical element.
Aerobic bacteria must have oxygen to live.

Nitrogen can be fixed by lightning during thunderstorms, a process that converts nitrogen gas (N2) into nitrates (NO3-) that can be used by plants. Nitrogen can also be fixed by certain soil bacteria called nitrogen-fixing bacteria, which convert N2 into a form that can be taken up by plants.
