Nitrogen Cycle Flashcard

Front

What is nitrogen fixation?

Back

Conversion of nitrogen gas into a usable form.

Front

Which organisms are responsible for nitrogen fixation?

Back

Bacteria and archaea.

Front

What is the process that turns nitrogen into ammonia?

Back

Nitrogen Fixation.

Front

What is the order of the nitrogen cycle?

Back

nitrogen fixation > assimilation > ammonification > nitrification > denitrification.

Front

What is the nitrogen cycle?

Back

Describes how nitrogen moves through the environment between living things, the soil, and the atmosphere.

Front

What role do bacteria play in the nitrogen cycle?

Back

They are essential for nitrogen fixation, nitrification, and denitrification.

Front

What is ammonification?

Back

The process of converting organic nitrogen into ammonia.

Front

What is nitrification?

Back

The process of converting ammonia into nitrites and then into nitrates.

Front

What is denitrification?

Back

The process of converting nitrates back into nitrogen gas.

Front

What is assimilation in the nitrogen cycle?

Back

The process by which plants and animals incorporate nitrogen into their tissues.
