Detailed explanation-1: -Answer. NITRIFYING BACTERIA has a direct and important role in the nitrogen cycle.
Detailed explanation-2: -Bacteria play a key role in the nitrogen cycle. Some species of nitrogen-fixing bacteria are free-living in soil or water, while others are beneficial symbionts that live inside of plants.
Detailed explanation-3: -Overview: The nitrogen cycle involves three major steps: nitrogen fixation, nitrification, and denitrification.
Detailed explanation-4: -Which of the following is most directly responsible for nitrogen fixation? Explanation: Nitrogen fixation is mostly done by bacteria living in the soil. Plants need nitrogen to grow, but they cannot use it straight from the atmosphere or as ammonia from the soil.
Detailed explanation-5: -Four processes participate in the cycling of nitrogen through the biosphere: (1) nitrogen fixation, (2) decay, (3) nitrification, and (4) denitrification.
