CED (pg.37)
TRUE OR FALSE
Specialist tend to be advantaged in habitats that are changing.
FALSE
CED (pg. 64)
What is tragedy of the commons?
Individuals that will used shared resources in their self-interest rather than keeping with the common good, therefore depleting resources. CED (pg. 95)
What are wet and dry scrubbers?
They are air pollution control devices that remove particulates and/or gases from industrial exhaust streams.
CED (pg. 147)
What will happen if the stratosphere ozone depletes?
An increase of UV rays will reach the Earth’s surface and can lead to skin cancer and/or cataracts if exposed to it.
CED (pg. 182)
What is nitrogen fixation?
Nitrogen fixation is the process in which atmospheric nitrogen is converted into a form of nitrogen (primarily ammonia) that is available for uptake by plants and that can be synthesized into any plant tissue
CED (pg. 40)
K-Species tend to be what?
Large, have fewer offspring, live in stable environments, spend their time with their offspring, mature after many years if parental care, long life spans, and reproduce more than once.
CED (pg.65)
What can overgrazing cause?
Overgrazing causes Desertification.
CED (pg. 103)
Where can indoor air pollutants come from?
Indoor air pollutants can come from natural sources, human made sources, and combustion.
CED (pg. 145)
A decrease of pH in oceans is what?
Ocean Acidification
CED (pg. 189)
In a marine biome, what supplies a large portion of Earth’s oxygen?
Algae
CED (pg.38)
Biotic potential refers to what?
Refers to the maximum reproductive rate of a population in ideal conditions.
CED (pg. 65)
What are the types of irrigation systems?
CED (pg. 99)
What does thermal inversion do?
Thermal Inversion traps pollution close to the ground. (Especially smog and particulates.
CED (pg. 143)
Carbon Dioxide has a global warming potential of what number?
GWP 1
CED (pg. 184)
TRUE OR FALSE
The phosphorus cycle has an atmospheric component.
FALSE
CED (pg.41)
What type of curve do r-selected species tend to follow?
Type III curve
CED (pg. 67)
Mechanization of farming does what?
Increase profits, efficiency for farms and increase reliance of fossil fuels.
CED (pg. 97)
How does photochemical smog form?
When nitrogen oxides and Volatile organic hydrocarbons react with heat and sunlight to produce a variety of pollutants.
CED (pg. 141)
What has the highest global warming potential (GWP)?
Chlorofluorocarbons (CFCs)
CED (pg. 184)
Lets say that plants and trees capture a lot of solar energy. They produce 3,000 grams of organic matter per square meter. But because of how hot the tropical rainforest is, they respirate 1,800 grams to stay alive. What is the Net Primary Productivity?
(Gross Primary Productivity):3000
(Respiration):1800
3000-1800=1,200
Total Net Primary Productivity is 1,200
CED (pg. 43)
If the growth rate of a population is 1.5% in 2020. Then what will be the doubling time?
70/1.5=46.667
So ~47 years
CED (pg. 72)
If a shared pasture can support 100 cows sustainably, but 10 farmers each bring 12 cows, how many cows over the limit is the pasture?
10×12=120 cows.
120−100= 20 cows over the limit
CED (pg. 95)
if the EPA limit for Lead is 0.015 ppm, what is that in ppb?
(1 ppm= 1,000 ppb)
0.015×1,000=15 ppb
CED (pg. 144)
If the total surface area of the ocean is 3.6×1014m2 and the volume of water increases by 7.2×1011m3 due to thermal expansion, how many meters will the sea level rise?
H= 7.2 x 10^11m3 / 3.6 x 10^14 m2 = 2 x10^-2 which is equal to 0.002m
