• It provides immediate energy for cells.

• It helps with breathing and oxygen transport.

What is the process called when atmospheric nitrogen is converted into ammonia by bacteria or lightning?

• Denitrification

• Nitrification

• Nitrogen Fixation

• Assimilation

Which type of bacteria converts nitrites into nitrates in the soil?

• Decomposers

• Denitrifying bacteria

• Nitrogen-fixing bacteria

• Nitrifying bacteria

What happens to nitrogen in dead animals and animal waste?

• It is immediately released back into the atmosphere.

• It is absorbed directly by plants.
