APES Biogeochemical cycles

Nitrogen fixation deals with....

• bacteria coverting Nitrates to Ammonia then back to Nitrogen as it moves back into the atmosphere

• Plants absorbing Ammonium and Nitrates

• Bacteria converting atmospheric Nitrogen into ammonia in the roots of legumes

• bacteria converting ammonia to nitrates

During denitrification.....

• bacteria found in roots of legumes converts atmospheric nitrogen to ammonium

• plants absorb ammonium and nitrates

• bacteria convert nitrates to ammonium then back to atmospheric nitrogen

• bacteria convert ammonium to nitrates

The biggest threat to the environment from excessive Sulfur is......

• global warming

• acid rain

• algal blooms in lakes

• burning gasoline

• animal waste

One natural source of sulfur into the atmosphere is.........

• earthquakes

• volcanoes

• hurricanes

• tornados

Excessive carbon in the atmosphere is a problem because.....
