Bacteria are a necessary part of the nitrogen cycle because living things cannot use atmospheric nitrogen.
Further Explanation:
The nitrogen cycle is the series of processes that lead to the interconversion of nitrogen and its compounds in the atmosphere. Bacteria are required in the nitrogen cycle because atmospheric nitrogen cannot directly use by the plant. Amino acids can be formed by the combination of ammonium ion and carbon skeletons. The anaerobes like Clostridium and facultative gram-negative enteric species of Klebsiella and salmonella are few nitrogen-fixing bacteria found in the soil. There can also be a symbiotic association of organisms, such as rhizobial bacteria and legumes, which aid in nitrogen fixation. Cyanobacteria are the main nitrogen fixers in the ocean and freshwater. Nitrifiers quickly oxidize the fixed form of nitrogen into nitrate or nitrite to nitrate by the process of nitrification.
Bacteria play a crucial role:
• Nitrogen-fixing bacteria transform the atmospheric nitrogen to nitrates.
• Bacteria of decay transform decaying nitrogen waste to the ammonia.
• Nitrifying bacteria transform ammonia into the nitrates/nitrites.
• Denitrifying bacteria mainly convert nitrates to nitrogen gas.

A small microscopic organism with one cell are called bacteria, they are essential for the ecosystem as they play a major role in the biochemical process.
Bacteria are a necessary part of the nitrogen cycle as other living organisms cannot directly use atmospheric nitrogen.
The cyclic process and the movement of the organic and inorganic nitrogen molecules through the various spheres of the earth are called the nitrogen cycle.
Bacteria are an essential part of the nitrogen cycle as they fix the atmospheric nitrogen for use by plants. Plants cannot directly utilize atmospheric nitrogen gas and require certain factors or molecules to convert them into useful elements that can be used.
The anaerobic and facultative bacteria fix the atmospheric gas into the various compounds in the soil. Certain bacteria convert the nitrogen into nitrates, ammonia, and nitrites so that the plants can use them for the processes.
Therefore, bacteria fix the atmospheric nitrogen gas.
