  1. Terrestrial biomes, Aquatic biomes, Plate tectonics Lecture Quiz 3 Jeopardy

  2. Final Jeopardy!

  3. What categories of organisms would you find at the first second and third trophic level? Growin’ Stuff $200

  4. Level 1: Primary Producers/AutotrophsLevel 2: Primary Consumers / Heterotrophs/HerbivoresLevel 3: Secondary Consumers / Heterotrophs/Primary Carnivores

  5. GPP is 200, Autotroph respiration is 85, Heterotroph respiration is 65. What is the Net Primary Production? How much of energy is available for plant growth? • Growin’ Stuff • $400

  6. NPP = 115115 units are available for growth

  7. What was the big concept focused on in the book about DDT effects on birds and mammals? What was that book called, and who was the author? • Growin’ Stuff • $600

  8. BiomagnificationSilent Spring, by Rachel Carson

  9. What is the limiting factor in bottom-up control, and what is the limiting factor for top-down control? • Growin’ Stuff • $800

  10. Top-down control is limited by consumersBottom-up control is limited by rescources that limit Primary Production (ex. Nutrients)

  11. What is the difference between the use of NPP in grasslands and the use of NPP in tropical rainforest? • Growin’ Stuff • $1000

  12. Grasslands will devote most of their available NPP to their undergrowth, whereas tropical rainforests will devote most of their available NPP to their overgrowth

  13. What is the driving force of the carbon cycle? • Got Gas? • $200

  14. Energy from sunlight

  15. Which nutrient cycles contain a gaseous state, and which do not? • Got Gas? • $400

  16. Carbon and Nitrogen contain a gaseous cycle,Phosphorous does not

  17. If the residence time of a nutrient is 5 years, and the input rate is 80 kg/year, what is the expected amount of that nutrient in the pool • Got Gas? • $600

  18. 400 kg

  19. What is/are the major pools of each nutrient discussed in class? • Got Gas? • $800

  20. Carbon: Atmospheric CO2Nitrogen: Atmospheric Dinitrogen Gas (N2)Phosphorous: Apatite in the soil (originating from parent material: bedrock)

  21. Define the term hypoxia, and describe what the Gulf Action Plan is expecting to achieve • Got Gas? • $1000

  22. A deficiency of oxygen in a given zone of deep water causing high mortality.The Gulf Action Plan means to reduce riverine nitrogen and phosphorous loads by 45%

  23. How does absorptivity relate to emissivity? Whose law refers to this relationship? • Let’s Get Physical • $200

  24. Absorptivity = EmissivityKirchoff’s Law

  25. How does available UV radiation change with elevation? • Let’s Get Physical • $400

  26. The atmosphere absorbs UV rays decreasing UV radiation as elevation decreases

  27. What are the three pathways radiation may take after hitting an object? How will those pathways vary with the nature of the material and angle of incidence? • Let’s Get Physical • $600

  28. Radiation can be absorbed, transmitted, or reflected by an objectDifferent materials absorb or reflect better than others, and as the angle of incidence decreases, more radiation will be reflected rather than transmitted

  29. Why does the sky appear blue during the day, and why would the sky appear red at sunrise/set? • Let’s Get Physical • $800

  30. Small molecules of air scatter blue wavelengths of light during midday (called Rayliegh scattering), whereas larger particles such as dust scatter red wavelengthsAt sunrise/set, a greater path length of the light allows for greater scattering of blue light away from us, leaving red light to reach us

  31. Why do leaves absorb visible and far infrared radiation very well, but absorb near infrared radiation very poorly? • Let’s Get Physical • $1000

  32. Visible light has a high energy that is capable of exciting electrons for photosynthesis, whereas near infrared radiation does not have enough energy to excite the electrons. Because plants are good emitters of longwave radiation (far infrared), the are therefore good absorbers of longwave radiation.

  33. What Is the General Transport Equation? • Lecture 11 • $200

  34. Flux density = Conductance x Driving Force(total amount) = (how easily it can be pushed) x (how much force is pushing it)

  35. Define the term wind chill, and describe under what conditions does wind chill actually matter? • Lecture 11 • $400

  36. Wind chill is the effect of decreased temperature due to high wind speeds, but it only relates to organisms that have a body temperature different than the surround temperature

  37. How is a boundary layer affected by each organism size, fluid velocity, and fluid viscosity? • Lecture 11 • $600

  38. A larger organism would have a thicker boundary layerLower fluid velocity would have a thicker boundary layerHigher viscosity would have a thicker boundary layer

  39. Define the 5 different ways by which heat energy can be transferred, and describe how at least 3 of those processes work • Lecture 11 • $800

  40. Radiation: Bodies emit radiation relative to temperatureConductance: Transfer along a heat gradient; hotter molecules vibrate and bump into cooler molecules, heating them upConvection: Transfer through fluid motionEvaporation: Heat is transferred to water to turnit into vaporCondensation: Heat transfers from water vapor to turn it back into water

  41. Describe what the Reynolds number refers to, and define what a low Reynolds number would mean? • Lecture 11 • $1000

  42. The Reynold’s Number refers to the nature of flow of a fluid around an objectA low number means laminar flow is present, the object is small/slow, and the fluid might be more viscous

  43. Define Chemoautotrophy and give an example of organism that undergoes it • Big Words • $200

  44. The formation of chemical energy via the fixation of inorganic materialsBacteria living in the ocean vents that use sulfur to take in CO2

  45. DOUBLE DOWN

  46. Define succession, at what stage of succession will NPP be at its greatest? • Big Words • $400 Define the term Keystone Species, and give one example of a keystone species discussed in lecture?

  47. Keystone species: A species that has a greater impact on its environment than its dominance might suggestPisaster(starfish); shown in the experiments done by Robert Paine

  48. Define the First and Second Laws of Thermodynamics • Big Words • $600

  49. First Law: Energy and matter can neither be created nor destroyedSecond Law: Energy loses its ability to do work as is degraded in quality during each conversion process

  50. Define the terms Nitrogen Fixation, Nitrification, and Denitrification • Big Words • $800
