Carbon Cycle
Identify TWO long term carbon reservoir.
Oceans, Algae, Fossil Fuels, Sediment, trees
What is a natural source of nitrogen?
Volcano, lightening
What is the driving factor of the water cycle?
The sun
Biomes are determined by these two factors
Temperature and precipitation (Climate)
What is the difference between food web and food chain?
Web shows multiple food chains, food chain shows one linear pathway
Identify two carbon sources
Fossil Fuels, Agriculture, deforestation
What is the process of N2 gas being converted into biologically available ammonia or nitrates
Nitrogen Fixation
The process of water trickling through soil down into groundwater aquifers
infiltration or percolation
What biome would have low primary productivitty?
Tundra, Desert,
The arrows in food webs indicate direction of what?
Energy transfer
What is the process used by plants and animals to release stored energy and emits CO2
Cellular respiration
The process where plants & animals taking N in and incorporating it into their body
Assimilation
The rate that solar energy is converted into org. compounds via photosynthesis over a unit of time
Primary Productivity
Areas where rivers empty into oceans, with brackish water
Estuaries
Identify an organism that is both a secondary and tertiary consumer
Buzzard, snake
How do coral reefs and marine organisms with shells use oceanic carbon?
Calcium carbonate for the shells
What is it called when nitrates runoff into local waters, causing algae blooms that block sun & kill other aq. plants
Eutrophication
How does the phosphorus cycle differs from Nitrogen and Carbon cycle?
Slower, rocks, weathering, no atmospheric component
What biome is fresh water body with soil submerged/saturated in water for at least part of the year?
Wetland
When the removal or addition of a top predator has a ripple effect down through lower trophic levels
Trophic cascade
Explain the process of burial of carbon?
slowly stores C in underground sinks like sedimentary rock or fossil fuels
What is the process where soil N (NO3) is converted into nitrous oxide (N2O) gas which returns to atmosphere
Denitrification
What are the three types of resource partitioning?
Spatial, temporal, morphological
What are two of the four characteristics of aquatic biomes
Salinity, Flow, Depth, Temperature
If the producers have 6500 kj of energy, how much energy will transfer to the tertiary consumers?
6.5 kj
