Biofertilizers convert nitrogen to ________ . A. Nitrates B. Ammonia C. Nitrogenase D. Amino acids

The correct answer is: A. Nitrates.

Biofertilizers are organisms that fix nitrogen from the atmosphere and make it available to plants. They do this by converting nitrogen gas into ammonia, which is then converted into nitrates by bacteria in the soil. Nitrates are the form of nitrogen that plants can use to grow.

Option B, ammonia, is a gas that is produced when nitrogen is fixed. However, it is not the form of nitrogen that plants can use. It must first be converted into nitrates by bacteria in the soil.

Option

Option D, amino acids, are the building blocks of proteins. They are not produced by biofertilizers.

In conclusion, biofertilizers convert nitrogen to nitrates. This makes nitrogen available to plants, which can then use it to grow.
