Question

[4] In whose presence do the bacteria not fix nitrogen?
​

Answer 1

Answer:

Presence of Cyanobacteria Anabaena and Nostoc are two types of bacteria that allow nitrogen fixing but increase of CO2 reduces the function of nitrogen fixation.

Answer 2

Presence do the bacteria not fix nitrogen are explained in the following:

• The bacteria of the Rhizobium genus are linked to nitrogen-fixing bacterium. These are anaerobic bacteria that fix nitrogen in the nonappearance of oxygen.
• Because it fixes inorganic nitrogen molecules that are necessary for the creation of all nitrogen-restraining biotic compounds, including as proteins and amino acids, nucleoside triphosphates nucleic acids, and nitrogenembed is a crucial life mechanism.
• Nitrogen embed is a natural procedure that involves the transformation of atmospheric nitrogen into ammonia and biotic compounds.
• This bacterium's nitrogenase enzyme aids in the altering of atmospheric nitrogen to nitrates, which may be optimized by plants for growth. In the non-appearance of oxygen, this enzyme is active, and nitrogen embed occurs. The obligatory anaerobic bacteria are involved in the nitrogen embedprocedure
• These nitrogenase enzymes are extremely important, yet they are rapidly damaged when exposed to oxygen. In the occupancy of oxygen, numerous bacteria stop producing enzymes.
• Numerous nitrogen-embed bacteria thrive in anaerobic environments, inhaling to reduce oxygen levels or conclusive oxygen to cytokine such as leg hemoglobin.
