An organism used as a biofertilizer for raising soyabean crop is
1 Azobacter
2 Azospirillum
3 Rhizobium
4 Nostoc
Explanation:
Rhizobium is a bacteria that live inside the root nodules of the leguminous plants. They form a symbiotic association with the plant. They fix the atmospheric nitrogen for the plants. They are used in soybean and pea plant fields as biofertilizers.

Fungi belonging to genus ____ takes part in mycorrhiza is ____
1 Glomus
2 Nostoc
3 Azolla
4 Ulothrix
Explanation:
Glomus is a genus of arbuscular mycorrhizal fungi which forms endomycorrhiza, a symbiotic association with plant roots. The fungal symbiont in these associations absorbs phosphorous from soil and passes it to the plant. Plants having such associations show other benefits also, such as resistance to rootborne pathogens, tolerance to salinity and drought and an overall increase in plant growth and development.
