Find the gases for which the following statements are related.

Gas interacting with the rhizobium bacteria in the soil

Nitrogen (N2)

The rhizobium bacteria are present in the root nodules of leguminous plants (like pea plants). They convert the atmospheric nitrogen into nitrogen compounds (like ammonia). In this form, plants are able to absorb these compounds that help in their growth. This process of converting atmosphere N2 into nitrogen compounds is called nitrogen fixation.
