Explanation:
The various groups or types of bacteria do play a crucial role in the nitrogen cycle. The nitrogen cycle is a biological process that converts nitrogen from the atmosphere into usable forms for plants and other organisms. Bacteria, including nitrogen-fixing bacteria, nitrifying bacteria, and denitrifying bacteria, are key players in this process. Nitrogen-fixing bacteria convert atmospheric nitrogen into ammonium, nitrifying bacteria convert ammonium into nitrate, and denitrifying bacteria convert nitrate back into atmospheric nitrogen. Therefore, their presence and activity are indispensable for the nitrogen cycle to occur.
