Organisms use nitrogen to form

• carbohydrates and lipids
• proteins and lipids
• lipids and nucleic acids
• proteins and nucleic acids

When nitrogen gas is turned in to a form that plants and animals can use is called 

• Combustion
• Photosynthesis
• Decomposition
• Nitrogen Fixation

What happens when organisms die and decay? 

• Their nitrogen moves to the air as nitrogen gas
• Their nitrogen returns to the soil as ammonium
• Their nitrogen becomes tapped in clay and is unusable
• They stay on earth forever

Carbon dioxide is added to the atmosphere by

• Burning fossil fuels 
• Cellular respiration
• Decomposing organic matter
• All answers are correct

If the atmosphere is 78% N₂, why can't we just get our nitrogen by breathing?

• We have no mechanism to break the triple bond of nitrogen between the atoms.
• Our lungs would be damaged by the N2.
• We need Oxygen for cellular respiration.
• The legumes take it up first.

The nitrogen found in the atmosphere is not in a form that plants or animals can use.  What converts it into a usable form?

• Bacteria
• Photosynthesis
• Decomposition of organisms
• Fungi
