Blue-green algae

Vedclass · Answer

(A) Biofertilizers are organisms that enrich the nutrient quality of the soil. Blue-green algae (cyanobacteria) are autotrophic microbes widely distributed in aquatic and terrestrial environments,many of which can fix atmospheric nitrogen,thereby increasing the nitrogen content of the soil and enhancing its fertility. Bt-cotton is a genetically modified crop resistant to pests,not a biofertilizer. Saccharomyces cerevisiae (yeast) is primarily used in the baking and brewing industries. Therefore,blue-green algae are the correct organisms used as biofertilizers.
