Some essential nitrogen compounds can be absorbed by plants from the soil in which they grow. the nitrogen compounds can be provided to the soil by nitrogen-fixing bacteria living in association with the plants and/or from fertilizers. Some nitrogen compounds can also be input to the soil from lightning strikes that provide activation energy to facilitate the reaction of atmospheric nitrogen to produce absorbable nitrogen compounds that can be carried into soil by rain.

BlakePlants obtain nitrogen compounds through the uptake of nitrate and ammonium ions from the soil through their root systems. Additionally, some plants have symbiotic relationships with nitrogen-fixing bacteria that convert atmospheric nitrogen into a form that can be used by the plants.

What are two ways that nitrogen is fixed so plants can use it?
Nitrogen can be fixed by symbiotic bacteria in root nodules of leguminous plants, converting atmospheric nitrogen into ammonium ions. Nitrogen can also be fixed through lightning strikes, which initiate a reaction that converts atmospheric nitrogen into nitrogen oxides that can be absorbed by plants.
What are two forms of fixed nitrogen?
Two forms of fixed nitrogen are ammonia (NH3) and nitrate (NO3-). Fixed nitrogen refers to nitrogen that has been converted from its inert atmospheric form (N2) into compounds that can be used by plants and other organisms.
What are the two ways nitrogen can be fixed?
Nitrogen can be fixed by lightning during thunderstorms, a process that converts nitrogen gas (N2) into nitrates (NO3-) that can be used by plants. Nitrogen can also be fixed by certain soil bacteria called nitrogen-fixing bacteria, which convert N2 into a form that can be taken up by plants.
Would two compounds made of nitrogen and oxygen always be identical?
No, two compounds made of nitrogen and oxygen would not always be identical. Different combinations of nitrogen and oxygen atoms can form different compounds with unique chemical and physical properties.
Is nitrogen a molecule or an atom?
Nitrogen exists as a diatomic molecule, meaning it is made up of two nitrogen atoms bonded together (N2). In its elemental form, nitrogen is a molecule, while nitrogen atoms can bond with other atoms to form various compounds.
