How is importance of bacteria for

the nitrogen cycleฺ์ห์ฺ์ฺ?

Bacteria are important because they perform the essential processes for the nitrogen cycle such as ammonification, nitrogen fixation, and nitrification.

As Nitrogen cant be used in its form due to its chemical form so it is transformed to various forms in the nitrogen cycle, bacteria helps in the process.

Why is leguminous crop rotation used in agriculture?

!

Leguminous crop rotation and other crop rotations are used in agriculture because in these plants many bacteria important for the nitrogen cycle live. The leguminous crop rotation (or conjointly with the main crop) helps the soil to become rich in nitrates that then are absorbed by the plants. Green manure, the covering of the soil with grass and leguminous, is a way to improve the fixation of nitrogen and it is an option to avoid chemical fertilizers.

The nitrogen cycle is important due to its role as a basis for the production of nitrogen that is essential to all forms of life. The atmosphere contains a vast majority of the natural nitrogen found on Earthใใ.

Which forms of nitrogen can be used by producers to produce protein and/or amino acid?

Nitrification

Nitrification is the conversion of ammonia (NH3) to nitrate (NO3-). It is usually performed by soil living bacteria, such as nitrobacter. This is important because plants can assimilate nitrate into their tissues, and they rely on bacteria to convert it from ammonia to a usable form. Nitrification is performed mainly by the genus of bacteria, Nitrobacter.
