This is fill in the blanks we should fill the blanks like a passage ​

Answer 1

Answer:

Plants need nitrogen for synthesising protein, but they cannot make use of free atmospheric nitrogen. They obtain it only in the form of nitrate ( NO₃⁻ ) from the soil through nitrogen fixing bacteria. The nitrates are replenished in the soil by bacteria through the process of fixation which converts the nitrogenous waste and dead remains of plant and animals first into ammonia (NH₃) and then to nitrate (NO₂⁻). This is brought about by bacteria such as Rhizobium and Nitrobacter.

More about nitrogen-fixing bacteria:

• A special category of soil bacteria such Rhizobium is found living in small nodules of the roots of leguminous plants, such as beans.
• These bacteria pick up free nitrogen from the soil and atmosphere and convert it into soluble nitrates.
• These nitrates are in turn used by the host plant and also by other plants sown later in the same soil.
