Biogeochemical cycle is defined as "the cycling of chemical elements between the atmosphere, hydrosphere, lithosphere, and biosphere"(Biology-Online.org)
Here are two biogeochemical cycles:
Here are two biogeochemical cycles:
Carbon Cycle
"The Carbon Cycle." WindowstotheUniverse.org. N.p., n.d. Web. 20 Dec. 2012.
· Carbon travels from the atmosphere to plants
o Photosynthesis
· Carbon travels from plants to animals
o Consumption
· Carbon travels from plants to animals to the ground
o Decomposition
· Carbon travels from organism to the atmosphere
o Respiration
· Carbon travels from fossil fuels to the atmosphere]
o When fuels are burned carbon is emitted into the atmosphere as CO2
· Carbon travels from the atmosphere to the oceans
o Bodies of water absorb carbon from the atmosphere
Nitrogen Cycle
"The Carbon Cycle." WindowstotheUniverse.org. N.p., n.d. Web. 20 Dec. 2012.
1. Fixation- most of fixation is done by bacteria
2. Uptake- when a nitro group is added to an organic compound
3. Mineralization- decomposers consume and break down organic matter and nitrogen is converted into ammonium
4. Nitrification- ammonium is converted to nitrate
5. Denitrification- denitrifying bacterie convert nitrate into dinotrogen that is released into the atmosphere
