Ecology Review Flashcards
Water Cycle Processes
7 PERTUPT
- Evaporation (over ocean, land)
- Precipitation (over ocean, land)
- Transpiration (plants → air)
- Run-off
- Uptake (soil → plants)
- Throughflow (groundwater → ocean)
- Percolation
Carbon Cycle Processes
8
- Biological & Chemical Processes (ex. bio carbon pump)
- Sedimentation (CO2 in oceans → organic sediment)
- Combustion (fossil fuels, producers → atm)
- Fossilization (sediment, decomposers → fossil fuels)
- Respiration (organisms w/ organic C)
- Photosynthesis (atm → producers)
- Feeding
- Death
Nitrogen Cycle Processes
9
- Nitrification
- Nitrogen Fixation
- Fossil Fuel combustion
- Denitrification
- Assimilation
- Leaching
- Death & Decomposition
- Ammonification
- Haber Process
Oxidation of ammonia & ammonium to nitrites and nitrates
Nitrification
How are anthropogenic sources convered to ammonia and ammonium
Haber Process
* converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using a metal catalyst under high temperatures and pressures.
What activity happens to convert Nitrites into Nitrates
Nitrobacter activity
Phosporus Cycle Processes
7
- Assimilation
- Death & Exretion
- Run-off
- Leaching
- Weathering & Mining
- Geological Uplift
- Sedimentation
List
Processes that bring phospate in rocks to phosphate in soil
2
Weathering
Mining
How do P in marine sedimentary rocks end up in phosphate rocks
Geological uplift
* raising of a land mass through geological activity such as earthquake
organic matter produced by the decomposition of organisms
Detritus
Process that connects detritus to marine sedimentary rocks
Sedimentation
* dead organisms are deposited to the bottom of ocean
* becomes marine sedimentary rocks
Sulfur Cycle Processes
12
- Fossil Fuel Combustion
- Feeding
- Wet and Dry Deposition
- Dimethyl sulphide and Sea spray
- Decomposition
- Uptake
- Weathering and erosion
- Run-off
- Sedimentation and Geologic Processes
- Volcanic Activity, Dust and biogenic gas
- Hydrothermal vents
- Mining and Extraction
Processes in between atmospheric sulfur and oceans
2
- Wet & Dry Deposition
- Dimethyl sulphide and sea spray
How does sulfur from the earth’s crust end up in our oceans?
Hydrothermal vents
* underwater hot seeps that form in areas of active volcanoes and seamounts
Where does Nitrogen fixation take place?
Atmosphere to geosphere (soil)
