Front

What is nitrogen fixation?

Back

The process of converting nitrogen gas (N₂) from the atmosphere into ammonia (NH₃) or related compounds in soil.

Front

What role do decomposers play in the nitrogen cycle?

Back

Decomposers break down dead organic matter, returning nitrogen to the soil and atmosphere.

Front

What is denitrification?

Back

The process by which bacteria convert nitrates (NO₃) back into nitrogen gas (N₂), releasing it into the atmosphere.

Front

What is the significance of ammonia (NH₃) in the nitrogen cycle?

Back

Ammonia is a form of nitrogen that plants can absorb and use for growth.

Front

What are nitrates (NO₃)?

Back

Nitrates are nitrogen compounds that plants can absorb, formed from the oxidation of ammonia.
