Answer: F
Nitrogen fixation is a process that occurs in all bacteria. T or F?

Nitrogen fixation is a chemical process by which molecular nitrogen in the air is converted into ammonia or related nitrogenous compounds in soil. Atmospheric nitrogen is molecular dinitrogen a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation or diazotrophy is an important microbially mediated process that converts dinitrogen gas to ammonia using the nitrogenase protein complex. Nitrogen fixation …

Nitrogen fixation is the process by which nitrogen in the air (N 2) is changed (converted) into ammonia (NH 3) or other nitrogenous compounds in the soil.. Nitrogen fixation is essential to life because nitrogen compounds are needed for making all nitrogen -containing organic compounds such as amino acids proteins and nucleic acids.. Atmospheric nitrogen is a relatively unreactive molecule.

The conversion of nitrogen gas (N 2) into nitrates and nitrites through atmospheric industrial and biological processes is called nitrogen fixation .Atmospheric nitrogen must be processed or "fixed" into a usable form to be taken up by plants.Between 5 and 10 billion kg per year are fixed by lightning strikes but most fixation is done by free-living or symbiotic bacteria known as ...
