Answer 1

D. Too much nitrogen would be bound up in the form of nitrates.

Step-by-step explanation:

denitrifying bacteria are microorganisms whose action results in the conversion of nitrates in the soil to free atmospheric nitrogen. If there are no functioning denitrifying bacteria, there will be excess nitrate in the soil.

Hope this helps :)
