The percentage of all human freshwater use for irrigation
(Topic 5.5 Irrigation methods pg: 107)
What is 70%
These are the three specific types of symbiosis defined as close, long-term interactions between two different species.
(Topic 1.1 Introduction to Ecosystems pg: 44)
What are mutualism, commensalism, and parasitism
Biodiversity is measured at these three levels: genetic, habitat, and this one, which refers to the variety of types of organisms.
(Topic 2.1 Introduction to Biodiversity pg: 60)
What is species diversity
There are five principal greenhouse gases: Carbon dioxide, methane, nitrous oxide, CFCs, and this one, which has a very short residence time.
(Topic 9.3 Greenhouse Gas Effect pg:192)
What is water vapor
Nuclear power is generated through this process, where atoms are split into smaller parts after being struck by a neutron.
(Topic 6.6 Nuclear Power pg: 133 & 134)
What is nuclear fission
This irrigation method involves digging trenches between crops rows
(Topic 5.5 Irrigation methods pg: 107)
what is furrow irrigation
there are 80 total organisms. If 25% of them are predators, this is the total number of prey organisms
(Topic 1.1 Introduction to Ecosystems pg: 44)
What is 60
Math: 80 times 0.25 = 20 predators
80 - 20 = prey
This specific term refers to the total number of different species found in a particular ecosystem.
(Topic 2.1 Introduction to Biodiversity pg: 60)
GWP stands for this
(Topic 9.3 Greenhouse Gas Effect pg:192)
Global Warming Potential
This isotope is stored in fuel rods and is the primary fuel source used for nuclear power generation.
(Topic 6.6 Nuclear Power pg: 133 & 134)
what is Uranium-235
If a farm pumps 1,000 gallons of water using a flood irrigation system that is 20% inefficient due to evaporation, this is the total number of gallons that actually reach the crops.
(Topic 5.5 Irrigation methods pg: 107)
What is 800 gallons
Math 1,000 - (1,000 x 0.20) = 800
According to the Enduring Understanding, ecosystems are the result of interactions between these two types of factors
(Topic 1.1 Introduction to Ecosystems pg: 44)
What are biotic and abiotic factors
A population of 1,000 sea otters experiences a "bottleneck" event, and 90% of the population is lost. This is the number of otters remaining to provide genetic diversity.
(Topic 2.1 Introduction to Biodiversity pg: 60)
what is 100
Math: 1000 times .10 = 100
Methane has a GWP of 25. If a factory releases 10 tons of methane, it has the same warming effect as releasing this many tons of carbon dioxide.
(Topic 9.3 Greenhouse Gas Effect pg:192)
What is 250 tons
Math: 25 times 10 = 250
While nuclear power is considered a clean energy source because it releases no air pollutants, it does release hazardous solid waste and this type of water-based pollution.
(Topic 6.6 Nuclear Power pg: 133 & 134)
What is thermal pollution
This environmental issue occurs when too much irrigation raises the water table, preventing plant roots from absorbing oxygen.
(Topic 5.5 Irrigation methods pg: 107)
What is waterlogging
This specific interaction occurs when two organisms or species both require the same limited resource, such as food or space.
(Topic 1.1 Introduction to Ecosystems pg: 44)
What is competition
When habitat loss occurs, this type of species—which has a narrow diet or specific habitat needs—is usually the first to go.
(Topic 2.1 Introduction to Biodiversity pg: 60)
What is a specialist
Of all the major greenhouse gases listed, this group of man-made chemicals has the highest Global Warming Potential.
(Topic 9.3 Greenhouse Gas Effect pg:192)
What are Chlorofluorocarbons (CFCs)
In a nuclear plant, fission releases heat to create steam; that steam is then used to spin this device, which ultimately generates electricity.
(Topic 6.6 Nuclear Power pg: 133 & 134)
What is a turbine
These are the four different types of irrigation methods.
(Topic 5.5 Irrigation methods pg: 107)
What is furrow, flood, spray, and drip irrigation.
This strategy allows species to reduce competition by using resources in different ways, places, or at different times.
(Topic 1.1 Introduction to Ecosystems pg: 44)
What is resource partitioning
This type of diversity within a population makes it more likely that the group can respond to environmental stressors like disease or climate change.
(Topic 2.1 Introduction to Biodiversity pg: 60)
What is genetic diversity
his gas is used as the reference point for the GWP scale and is assigned a value of exactly 1.
(Topic 9.3 Greenhouse Gas Effect pg:192)
What is Carbon dioxide (CO2)
A nuclear powerplant has a storage site that can hold 500 bundles of spent fuel rods. if the plant has already filled 325 of those slots this is the number of bundles they can still have before the site is full.
(Topic 6.6 Nuclear Power pg: 133 & 134)
What is 175
Math: 500 - 325 = 175
