What is the form of nitrogen that results from the process of ammonification?

Back

Ammonia

Front

What is the process by which nitrogen gas is converted into ammonia?

Back

Nitrogen fixation

Front

What role do nitrifying bacteria play in the nitrogen cycle?

Back

They convert ammonia into nitrites and then into nitrates.

Front

What is the significance of the nitrogen cycle in ecosystems?

Back

It recycles nitrogen, making it available for use by living organisms.

Front

What is denitrification and why is it important?

Back

Denitrification is the process by which nitrates are converted back into nitrogen gas, returning nitrogen to the atmosphere and completing the cycle.

Front

What is the difference between organic and inorganic nitrogen?

Back

Organic nitrogen is found in living organisms and their remains, while inorganic nitrogen includes forms like ammonia, nitrite, and nitrate.
