Burning, lightning strikes, and legumes all play an important role in the nitrogen cycle by helping remove nitrogen gas from the atmosphere and converting it into a usable form for plants. What is this process called?*1 pointTranspirationNitrogen fixationDenitrificationDecomposition

In the nitrogen cycle, which process converts atmospheric nitrogen into a form usable by plants?

Nitrogen is an essential part of the proteins and DNA of organisms. Although nitrogen gas makes up about 78% of Earth’s atmosphere, it is unavailable for use by organisms in its gaseous form. Only when nitrogen is absorbed by beneficial bacteria in the roots of legumes does it enter the pathways that carry it through biological communities.The processes of conversion of atmospheric nitrogen first into ammonium ions (NH4+) and then into nitrates (NO3–) are called respectively*1 pointnitrogen fixation and denitrificationnitrogen fixation and nitrificationammonification and nitrificationammonification and denitrification

The process of denitrification in the nitrogen cycle is responsible for:*1 pointConversion of nitrogen gas into ammoniaConversion of nitrates into nitrogen gasAbsorption of nitrogen compounds by plantsConversion of ammonia into nitrates

Some bacteria and archaea can convert atmospheric nitrogen (N2) into a usable form through a process calledMultiple choice question.nitrogen fixation.decomposition.denitrification.nitrification.

How do leguminous plants contribute to the nitrogen cycle?*1 pointThey absorb nitrogen compounds from the atmosphere.They facilitate denitrification in the soil.They fix nitrogen gas into ammonia.They release nitrates into the soil.
