    Solution

    (A) Nitrogen fixation carried out by enzyme (I) Nitrogenase: Nitrogenase is the enzyme responsible for catalyzing the conversion of atmospheric nitrogen (N2) into ammonia (NH3) or related compounds in the process of nitrogen fixation. (B) Conversion of organic N to NH4 (II) Ammonification: Ammonification is the microbial conversion of organic nitrogen compounds into ammonium (NH4+), which is a form of nitrogen that plants can absorb. (C) Phosphate mobilizer (III) VAM (Vesicular Arbuscular Mycorrhiza): VAM, or mycorrhizal fungi, can enhance the uptake of phosphorus by plants by mobilizing phosphate in the soil and facilitating its absorption by plant roots. (D) Phosphate solubilizer (IV) Pseudomonas: Some species of Pseudomonas bacteria are known for their ability to solubilize phosphate in the soil, making it more available for plant uptake.
