1.4 - 1.7 Flashcards
Which carbon sinks Takes in C > releases
Oceans, plants (trees), soil
Which carbon source releases C > releases
FF Combustion (oil, coal) burn into C
Deforestation releases CO2
Animal agriculture (cow burp + fart = CH4)
Photosynthesis
CO2 sink or source?
This is quick process
6CO2 + 6O2 –> C6 H12 06 + 6O2
CO2 SINK
Cellular Resp
CO2 sink or source?
This is quick process
backwards + energy
Cellular resp is a CO2 source
Where is C stored?
Atmosphere and Ocean
What does decomposition do?
Whale sinks –> sedimentation –> burial = rocks of C after years
(releases C)
decomposition returns CO2 to atm
returns C to soil or water thru breakdown of sugars in bodies theyre decomposing
Coal is made of?
dead animals
Fast carbon cycling
movement of carbon compounds thru biosphere
Slow uplifting returns to C cycle
UpLIFTING C
Phosphorus
WRSLUMA=
NOT in atmosphere. Major reservoir is rock sedimentation
SLOWEST cycle
Importance?:
Sources
Sinks
LONGEST= years to weather; rocks that runoff into H2O takes years to become soil
1) Weathering 2) Runoff 3) Sedimentation 4) Lithification 5) Uplift 6) Mix rock and dead leaves=soil 7) Plants assimilate (P growth regulates plants) –> animals assimilate
WRSLUMA
P sustains bone and tooth enamel composition of animals
Sedimentary rocks
Sedimentary rocks, soil, oceans
Nitrogen
1) Fixation (Biotic: Rhizobacteria ; Abiotic: Lightning)
2) Ammonification 3) Nitrification
4) Assimilation 5) Denitrification
FANAD
Limiting factor
Needed but scarce
Difference between
soil
sediments
soil: mix of organic things
sediments:fragments/pieces of rocks
