nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.

Mar 14, 2018 · Answer: The bacteria convert free nitrogen into nitrogen-containing compounds, while the decomposers convert nitrogen-containing compounds into free nitrogen. Explanation: Nitrogen is an essential element for all living organisms. It is required for synthesis protein and nucleic acids and other nitrogenous compounds.
Some bacteria live in the roots of plants like soybeans and peas. What is the role of these bacteria in the nitrogen cycle? to absorb nitrogen-containing compounds from the soil to release free nitrogen into the atmosphere to break down nitrogen-containing compounds in dead organisms to convert free nitrogen into usable nitrogen
Mar 21, 2024 · Bacteria, such as cyanobacteria, convert nitrogen into nitrogen gas via nitrogen fixation. Nitrogen fixation occurs in three steps: ammonification, nitrification, and denitrification. Human activity can release nitrogen into the environment by the combustion of fossil fuels and by the use of artificial fertilizers in agriculture.
Apr 21, 2024 · In the nitrogen cycle, nitrogen-fixing bacteria convert atmospheric nitrogen into ammonia (ammonification). The ammonia can then be oxidized to nitrite and nitrate (nitrification). Nitrates can then be assimilated by plants. Soil bacteria convert nitrate back to nitrogen gas (denitrification).
Feb 5, 2018 · Atmospheric dinitrogen gas is the largest inventory of freely accessible nitrogen, and it is biologically available to highly diverse but rare nitrogen-fixing bacteria and archaea.

Dec 24, 2022 · Learning Objectives. Describe the importance of nitrogen fixation. Nitrogen fixation also refers to other biological conversions of nitrogen, such as its conversion to nitrogen dioxide. Nitrogen fixation is a process by which nitrogen (N 2) in the atmosphere is converted into ammonia (NH 3).
