oxygen

Explanation:

Answer 2

Some nitrogen-fixing bacteria do not perform nitrogen-fixing action

• Although the presence of Cyanobacteria Anabaena and Nostoc bacteria allows for nitrogen fixation, the function of nitrogen fixation is reduced when CO2 levels rise.
• Because it fixes inorganic nitrogen molecules that are necessary for the creation of all nitrogen-containing organic compounds, including amino acids and proteins, nucleoside triphosphates, including nitrogen fixation and nucleic acids is a crucial life mechanism. Nitrogen fixation would be a natural process that involves the transformation of air nitrogen into ammonia or organic compounds.
• Nitrogen fixation can be known as the procedure of transferring atomic nitrogen into ammonia, a substance that symbiotic systems might utilize. Natural nitrogen fixation occurs in soil by diazotrophic microorganisms including Azotobacter or Archaea. They have a symbiotic connection with leguminous plant root nodules.
• This bacterium's nitrogenase enzyme aids in the translation of air nitrogen to nitrates, which may be utilized by plants for growth. In the lack of oxygen, this enzyme is active, and nitrogen-fixing occurs.
• The necessary anaerobic bacteria are engaged in the nitrogen fixation process. These nitrogenase enzymes are extremely important, yet they are rapidly damaged when exposed to oxygen. In the existence of oxygen, many bacteria stop producing enzymes. Several nitrogen-fixing microorganisms grow in anaerobic environments, respiring to reduce oxygen levels as well as binding oxygen to proteins such as leg hemoglobin.
