The conversion of nitrates into atmospheric nitrogen is facilitated by microbes in a process called

This process is called Denitrification. The process is undertaken by the denitrifying bacteria, whose action is converting nitrates in the soil to free atmospheric nitrogen and therefore, depleting soil fertility and reducing agricultural productivity. Examples of denitrifying bacteria are thiobacillus denitrificans, micrococcus denitrificans among others.

The correct answer option is A. produce ATP.

Explanation:

Carbohydrates are important in the body because they contribute to the body's ability to produce ATP.

When a person eats food, that food is digested by breaking down the carbohydrates to in turn produce an energy rich component called ATP (adenosine triphosphate).

The carbohydrates are broken down by certain enzymes in the small intestine in the form of glucose which then yields ATP to drive the cell.
