145 WAYS TO GO APE

1. An external cost is not considered in the pricing of a product and is damaging to the environment or people's health.
2. High Quality Energy: organized & concentrated, can perform useful work (ex fossil fuel & nuclear)
3. Low Quality Energy: disorganized, dispersed (heat in ocean or air wind, solar)
4. First Law of Thermodynamics: energy is neither created nor destroyed, but may be converted from one form to another
5. Second Law of Thermodynamics: when energy is changed from one form to another, some useful energy is always degraded into lower quality energy (usually heat)
6. Ecosystem services are the positive attributes that nature provides for our wellbeing and health such as bats eating mosquitos and swamps cleaning water.
7. Half life: the time it takes for 1/2 the mass of a radioisotope to decay
8. Estimate of how long a radioactive isotope must be stored until it decays to a safe level: approximately 10 half-lives
9. Nuclear Fission: nuclei of isotopes split apart when struck by neutrons
10. Nuclear Fusion: 2 isotopes of light elements (H) forced together at high temperatures till they fuse to form a heavier nucleus. Expensive, break even point not reached yet
11. Tropical rain forests have very poor soils while grasslands have a very deep A-horizon (topsoil) that is rich in humus.
12. Mineral Reserve: identified deposits currently profitable to extract
13. Best solution to Energy shortage: conservation and increase efficiency
14. Surface mining: cheaper & can remove more mineral, less hazardous to workers
15. Humus: organic, dark material remaining after decomposition by microorganisms
16. Leaching: removal of dissolved materials from soil by water moving downwards
17. Illuviation: deposit of leached material in lower soil layers (B)
18. Loam: perfect agricultural soil with equal portions of sand, silt, clay
19. Solutions to soil problems: conservation tillage, crop rotation, contour plowing, organic fertilizers
20. Parts of the hydrologic cycle: evaporation, transpiration, runoff, condensation, precipitation, infiltration
21. Sandy soil drains quickly while soil filled with clay is best for retaining water.
22. Eutrophication is called by fertilizer or sewage in water bodies. The nutrients cause an explosion of plant life followed by an excess of dead decaying plants. Aerobic bacteria break down the organic material but take all the oxygen out of the water leaving none for aquatic life. Water with a low dissolved oxygen is called hypoxic.
23. Salt water intrusion: near the coast, overpumping of groundwater causes saltwater to move into the acquifer
24. ENSO: El Nino Southern Oscillation, see-sawing of air pressure over the S. Pacific
25. During an El Nino year: trade winds weaken & warm water sloshed back to SA
During a Non El Nino year: Easterly trade winds and ocean currents pool warm water in the western Pacific, allowing upwelling of nutrient rich water off the West coast of South America
26. Effects of El Nino: upwelling decreases disrupting food chains, N US has mild winters, SW US has increased rainfall, less Atlantic Hurricanes
27. Nitrogen fixing: because atmospheric N cannot be used directly by plants it must first be converted into ammonia by bacteria
28. Ammonification: decomposers covert organic waste into ammonia
29. Nitrification: ammonia is converted to nitrate ions (NO-3)
30. Assimilation: inorganic N is converted into organic molecules such as DNA/amino acids & proteins
31. Denitrification: bacteria convert ammonia back into N
32. Phosphorus does not circulate as easily as N because: it does not exist as a gas, but is released by weathering of phosphate rocks
33. Because soils contain very little phosphorus: it is a major limiting factor for plant growth
34. Excess nitrogen and phosphorus is added to aquatic ecosystems by: runoff of animal wastes, fertilizer discharge of sewage
35. Photosynthesis: plants convert atmospheric C (CO2) into complex carbohydrates (glucose C6H12O6)
36. Aerobic respiration: oxygen consuming producers, consumers & decomposers break down complex organic compounds & convert C back into CO2
37. Largest reservoirs of C: carbonate rocks first, oceans second

39. Producer/Autotroph: photosynthetic life
40. Major trophic levels: producers-primary consumer-secondary consumer-tertiary consumer
41. Energy flow in food webs: only 10% of the usable energy is transferred
42. Why is only 10% transferred: usable energy lost as heat (2nd law of thermodynamics), not all biomass is digested & absorbed, predators expend energy to catch prey
43. Primary succession: development of communities in a lifeless area not previously inhabited by life (lava)
44. Secondary succession: life progresses where soil remains (clear cut forest)
45. Mutualism: symbiotic relationship where both partners benefit
46. Commensalism: symbiotic relationship where one partner benefits & the other is unaffected
47. Parasitism: relationship in which one partner obtains nutrients at the expense of the host
48. Biome: large distinct terrestrial region having similar climate, soil, plants & animals
49. Carrying capacity: the number of individuals that can be sustained in an area
50. R strategist: reproduce early, many small unprotected offspring
51. K strategist: reproduce late, few, cared for offspring
52. Natural selection: organisms that possess favorable adaptations pass them onto the next generation
53. Malthus: said human population cannot continue to increase..consequences will be war, famine & disease

56. World Population is: over 7 billion
57. Preindustrial stage: birth & death rates high, population grows slowly, infant mortality high
58. Transitional stage: death rate lower, better health care, population grows fast
59. Industrial stage: decline in birth rate, population growth slows
60. Postindustrial stage: low birth & death rates
61. Age structure diagrams: (broad base, rapid growth)(narrow base, negative growth)(uniform shape, zero growth)

68. Point vs non point sources: (Point, from specific location such as pipe)(Non-point, from over an area such as runoff)
69. BOD: biological oxygen demand, amount of dissolved oxygen needed by aerobic decomposers to break down organic materials
70. Eutrophication: rapid algal growth caused by an excess of N & P
71. Hypoxia: when aquatic plants die, the BOD rises as aerobic decomposers break down the plants, the DO drops & the water cannot support life

76. Nitrogen Oxides: (Source: auto exhaust) (Effects: acidification of lakes, respiratory irritation, leads to smog & ozone) ( Equation for acid formation: NO + O2 = NO2 + H2O = HNO3) (Reduction: catalytic converter)
77. Sulfur oxides: (Source: coal burning) (Effects: acid deposition, respiratory irritation, damages plants) (Equation for acid formation: SO2 + O2 = SO3 + H2O = H2SO4) (Reduction: scrubbers, burn low sulfur fuel)
78. Carbon oxides: (Source: auto exhaust, incomplete combustion) (Effects: CO binds to hemoglobin reducing bloods ability to carry O, CO2 contributes to global warming) (Reduction: catalytic converter, emission testing, oxygenated fuel, mass transit)
79. Ozone: (Formation: secondary pollutant, NO2+UV=NO+O O+O2=O3, with VOC's) (Effects: respiratory irritant, plant damage including phytoplankton) (Reduction: reduce NO emissions & VOCs) Ozone in the stratosphere reduces UV light from hitting the earth, but ozone in the troposphere is a deadly pollutant made from burning fossil fuels.

92. Incineration disadvantages: toxic emissions (polyvinyl chloride-dioxin), scrubbers & electrostatic precipitators needed, ash disposal
93. Best way to solve waste problem: reduce the amounts of waste at the source
94. Keystone species: species whose role in an ecosystem are more important than others
95. Indicator species: species that serve as early warnings that an ecosystem is being damaged
96. Most endangered species: have a small range, require large territory or live on an island
97. In natural ecosystems, 50-90% of pest species are kept under control by: predators, diseases, parasites
98. Fracking pollutes ground water with the highly toxic chemicals used to open the shale to release the gas. Any removed toxic water is stored in containment ponds and trucked to wastewater plants that do NOT successfully remove the toxic chemicals.
99. Pesticide pros: saves lives from insect transmitted disease, increases food supply, increases profits for farmers
100. Pesticide cons: genetic resistance, ecosystem imbalance, pesticide treadmill, persistence, bioaccumulation, biological magnification

113. Moderately restricted use land: National Wildlife Refuges
114. Restricted Use lands: National Parks, National Wilderness Preservation System
115. Volcanoes and Earthquakes occur: at plate boundaries (divergent, spreading, mid-ocean ridges) (convergent, trenches) (transform, sliding, San Andreas)
116. Survivorship Curves
Type I: low mortality at birth, survive to old age, and then die (humans, annual plants)
Type 11: uniform death rates, subject to predation (insects, birds)
Type III: high mortality at birth but long lifespans otherwise (turtles, trees)

117. Density dependent factors: competition, parasitism, predation
118. Density independent factors: fires, floods, extreme cold
119. Biotic potential: maximum amount of offspring a species can have
120. Effects of Global Warming: bleaching of coral reefs, animals and plants forced out of their current range, melting glaciers, rising sea level, droughts, spread of infectious diseases and more extreme weather conditions.
121. Species from another region become Invasive because they often can grow at an uncontrolled rate because they have no natural predators, disrupt the balance of the ecosystem and have no competition because they kill off many natural inhabitants.
122. Forests regulate climate, control water runoff, produce oxygen and provide food and shelter for many creatures.
123. Clear cutting is bad because it increases soil erosion dramatically, increases nitrate runoff into water bodies, makes it hard for an area to recover, leaves animals no place to live and can lead to extinctions.
124. Selective Cutting: harvesting only mature trees of certain species and size. More expensive but less disruptive to wildlife than clear cutting.
125. Wetlands purify water, control flooding, recharge groundwater, and is a habitat for many rare and endangered species.
126. Conservation is the management of a resource to make certain to produces the greatest benefit to humans in the future.
127. Preservation is the concept that the land should be kept in its natural state- never touched or developed.
128. NIMBY- public protests cause wastes and other pollutants to be dumped in someone else's backyard. Mostly hurts the poor who cannot pay for representation to fight against potential pollution.
129. Range of Tolerance: minimum and maximum levels of conditions in which organisms can survive.
130 1.5 billion people lack access to clean drinking water and 3 billion people lack good sanitation need to prevent communicable diseases from spreading.
131. 75% of water pollution in the US come from soil erosion, atmospheric deposition and surface run off.
132. 95% of water pollution in developing countries come from raw sewage (high population growth without the money for treatment plants)
133. The percent annual growth rate is the crude birth rate - crude death rate divided by 10.
134. The troposphere contains weather and stratosphere contains the ozone.
135. The atmosphere is 78% nitrogen, 21% oxygen, and a small amount of argon, carbon dioxide, water, salt and dust.
136. Density-dependent factors kill off species BECAUSE they are densely packed such as infectious diseases, density-independent species do not suffer proportionally more just because they are closer together.
137. Bioaccumulation is the selective absorption and storage of a great variety of molecules
138. Biomagnification is a continued increase in the concentration of pollutants in higher levels of a food chain.
139. Acute effects are caused by a single exposure to a toxin and results in an immediate health crisis of some sort.
140. Chronic effects are long lasting and can result from a single exposure of a very toxic substance or a continuous exposure to the toxin.
141. Intraspecitic competition is competion between the same species such as for food and mates. Interspecific competiion is competion between two different species which can also be food.
142. Watershed: land surface and groundwater aquifers drained by a particular river system.
143. A wide bottom to an age-structure diagram means the population will increase. An inverted pyramid means the population will decrease. A straight sided age-structure diagram means the population will remain steady.
144. 99% of all the species that ever existed are now extinct but the average rate of extinction was one species per decade.
145. Human have caused extinction rates of hundreds to thousands of species per YEAR. If these trends continue, 1/3 to 2/3 of all current species will be lost by the year 2050. (That is definitely a reason to go APE!!!)
