Water, Co2 And Nitrogen Cycles Flashcards
Name the five stage of the water cycle
Evaporation, condensation, presipitation, accumulation, runoff
Which stage of the water cycle do plants get there water from
Accumulation
Name 2 sources of water vapor
Bodies of water and plants
Draw and label the Co2 cycle
Name two ways plants directly contribute to Co2 in the atmosphere and one way they reduce it
Resperation, combustion and reduce it threw photosynthesis.
How do animals contribute to Co2 in the atmosphere
Resperation
Describe oh fossils relate to the caebon
Plants and animals die and become dead organic matter. They then have a chance of becoming fossils and fossil fuel which are burned by humans
Name 3 molecules that contain Nitrogen
Ameno acids, nucleic acids, chlorophytes
What is the chemical formula of ammonium
NH4
Name the 3 ways Nitrogen gets fixed from the atmosphere
Lightning Nitrogen fixing bacteria, blue/green alge
Name 3 ways Nitrogen gets fixed from the atmosphere
Blue/green alge, Nitrogen fixing bacteria, lightning
What happens to nitrogen after the blue green alge fixes it
The alge is eaten by fish and the Nitrogen is turned into animal proteins
What happens to nitrogen after it is fixed by bacteria
It is deposited into the soil and plant roots. From the plant roots it is turned into proteins which are then eaten buy animals and turned into animal proteins
What is the chemical formula of ammoia
NH3
What happens to animal proteins in the Nitrogen cycle
They are released via animal feaces and death and turned into ammonia via amonification
What is the role of nitrifying bacteria
To turn ammonia into nitrite
What is the chemical formula for nitrite
NO2-
What happens to nitrite in the Nitrogen cycle
It is turned into nitrate via nitrification
Name 3 sources of nitrate
Lightning, organic fertilizer, nitrite nitrification
Name 2 places nitrates can end up as part of the Nitrogen cycle
Plant proteins and N2 in the atmosphere
Name one other source of atmospheric N2
Valcanos
