Answer:
Explanation: Bacteria are microscopic single cell organism.
For farmers Bacterial are important tools in Nitrogen cycle. It helps in Fixing of nitrogen into the soil in the root noodles of some leguminous crop.Bacterial contains Nitrogenous enzyme the combines with atmospheric Nitrogen to fix ammonia which is further converted to other organic compounds and Nitrogen.
Bacterial also act on dead plant and animal converting the inorganic Nitrogen to ammonia which is further broken down to Nitrogen.
Some important bacterial include Nitrogen Fixing bacterial,Azotobacter
Without the activity of bacteria Nitrogen level or concentration would be reduced and not available for plant uptake.
Answer:
Bacteria are able to produce ammonia and nitrates starting with the abundant nitrogen Gas in the atmosphere. These components are critical to plant survival, and are accessible because they are located in the soil where they can be absorbed by plant roots. Without bacteria, the nitrogen pulled from the soil by plants would not be replaced. Eventually, the plants would run out of ammonia and nitrates and would no longer be able to survive.
