Fill in the blank in the part of Nitrogen cycle drawn below;
Leguminous plants
Atmospheric Nitrogen
Soil Nitrates
a) Nitrifying bacteria sticking to roots of leguminous plants
b) Nitrifying bacteria in soil.
c) Nitrogen fixing bacteria in root nodules of leguminous plants
d) Nitrogen fixing bacteria in soil.



Answer :

Final answer:

Nitrogen-fixing bacteria in the root nodules of legumes and soil are essential for converting atmospheric nitrogen into usable forms for plants in the nitrogen cycle.


Explanation:

In the nitrogen cycle, nitrogen-fixing bacteria play a crucial role in converting atmospheric nitrogen into forms usable by plants. Specifically, nitrogen-fixing bacteria exist both in the root nodules of legumes and in the soil, allowing for the conversion of nitrogen gas into ammonium. This process makes nitrogen available to plants, ultimately impacting the entire nitrogen cycle.
