[amp_mcq option1=”Yeast” option2=”Chlorella” option3=”Azolla” option4=”Mold” correct=”option3″]<\/p>\n

The correct answer is (c) Azolla.<\/p>\n

Azolla is a small, free-floating fern that grows in freshwater. It is a popular biofertilizer because it can fix nitrogen from the air, which is essential for plant growth. Azolla is also a good source of protein and other nutrients for fish and other aquatic animals.<\/p>\n

Yeast is a single-celled fungus that is used in baking, brewing, and winemaking. It is not a source of biofertilizer.<\/p>\n

Chlorella is a green algae that is used as a food supplement and a source of biofuel. It is not a source of biofertilizer.<\/p>\n

Mold is a fungus that can grow on food, wood, and other organic materials. It is not a source of biofertilizer.<\/p>\n

Here is a table that summarizes the information about each option:<\/p>\n

| Option | Description | Is a source of biofertilizer? |
