Topic 1: Foundations
A model that shows the inputs affecting our perspectives and the outputs resulting from our perpsectives
What is the Environmental Value System (EVS)
A particular set of conditions needed by an organism or population.
What is a niche?
A body of porous rock or sediment saturated with groundwater.
What is an aquifer?
Stores more carbon than the atmosphere and all of the earth's plants and forests combined.
What are soils?
A process that occurs when gases in the Earth's atmosphere trap the sun's heat energy.
What is the Greenhouse Effect?
Puts Ecology and nature central to humanity and emphasizes a less materialistic approach to life
Who is an ecocentric?
The naming and classifying of organisms both living and extinct.
What is taxonomy?
A quantitative estimate of the amount of water in stores and flows of the water cycle.
What is a water budget?
O, A, E, B, C, R
What is a soil profile? (soil horizons)
Water vapor, Carbon dioxide and methane
What are the main Greenhouse gases?
N and O are not greenhouse gases
A measure of how much a surface reflects.
What is albedo?
What are the two variables that determine the shape of a population curve? (2.1)
What is K and r-strategists' reproductive strategies?
Access to a sufficient quantity of clean water to live sustainably.
What is water security? (4.2)
Uses no synthetic fertilizers or chemicals and no genetically modified plants or animals.
What is organic farming?
Creates legally binding obligations as international law. Used for agreements less formal than a "treaty" or "convention".
What is a UN protocol?
Occurs when a disturbance leads to an amplification of that disturbance and destabilizes the system
What is a positive Feedback loop?
The sustainable use and management of natural resources.
What is conservation biology?
These type of crops require less water but still provide the required yield.
What are drought resistant crops?
This mode of farming long followed in the humid tropics of sub-Saharan Africa, Southeast Asia, and South America. In this practice of slash and burn, farmers would cut the native vegetation and burn it, then plant crops in the exposed, ash-fertilized soil for two or three seasons in succession.
What is shifting cultivation?
Having a balance between emitting carbon and absorbing carbon from the atmosphere in carbon sinks.
What is carbon neutrality?
When materials can be made and used but then reuse, repair, remake, and remove waste and regenerate natural systems. (1.3)
What is the circular economy model?
D= N(N-1)/sum_n(n-1)
What is Simpson's reciprocal index (species diversity)
Bottom trawling, gill nets, purse seine nets, blast or dynamite fishing, ghost fishing.
What are some Methods used to catch fish that are highly destructive? (4.3)
soil erosion, salinization, desertification, urbanization
What are some factors that decrease agricultural land? (decrease food supply, unsustainable) 5.2
This is where most reactions affecting life occur, ex ozone formation and cloud formation.
What is the troposphere and stratosphere?
