How do the following organisms act as bio-fertilizers? Explain.
(a) Mycorrhiza
(b) Anabaena
(c) Rhizobium
(a) Mycorrhiza
(b) Anabaena
(c) Rhizobium
Show Hint
Solution and Explanation
Mycorrhiza: A symbiotic association between fungi and plant roots. Enhances water and nutrient absorption, particularly phosphorus.
Anabaena: A cyanobacterium capable of nitrogen fixation. Provides nitrogen to plants in a usable form and enhances soil fertility.
Rhizobium: A bacterium that forms nodules on the roots of leguminous plants. Converts atmospheric nitrogen into ammonia, which is used by the plant.
