Mineral Cycles

The following processes are essential to the nitrogen cycle. Briefly describe each.: Denitrification

• The  process  of  converting  atmospheric   nitrogen  gas  to  nitrates  and  ammonia. 

• The  production  of  ammonia  by  bacteria   during  the  decay  of  nitrogen  containing  organic  matter. 

• The  production  of  nitrates  from  ammonia.

• The  absorption  and  incorporatIon  of  nitrogen   into  plant  and  animal  compounds.

• The  conversion  of  nitrates  to  nitrogen  gas.

The nitrogen cycle requires 4 different types of bacteria.  What is the role of Nitrogen Fixing bacteria?

• Take  atmospheric  nitrogen  and   convert  it  to  ammonia.

• These  are  decomposers.    They  break   down  dead organic  matter  and  convert  it  to  ammonia.

• Convert  ammonia  to  nitrates.

• These  bacteria  consume  nitrates  and   release  elemental  nitrogen  back  into  the  atmosphere.

At any given Time, the water on Earth can be found in various  reservoirs.  Name these reservoirs of water. Reservoirs include: 

• Bodies of water such as oceans, lakes and rivers

• Stored in the bodies of living organisms

• In the atmosphere as clouds and water vapor

• Stored in groundwater
