3. Poor nutrition that results from an insufficient or poorly balanced diet.






4. Open or forested areas built at the outer edge of a city.

7. A semiconductor device that converts the energy of sunlight into electric energy.






8. The dosage level of a toxin at which a negative effect occurs.






9. The part of the mantle that lies just below the lithosphere.






10. The form petroleum takes when in the ground.






11. The removal of all of the trees in an area.






12. An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.






13. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






14. An animal that only consumes other animals.






15. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.

17. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






18. Any compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






19. The molten core of the Earth.






20. A fiscal policy that lowers taxes on income - including wages and profit - and raises taxes on consumption - particularly the unsustainable consumption of non-renewable resources.






21. The least pure coal.






22. When soil becomes water-logged and then dries out - and salt forms a layer on its surface.






23. The result of graphing a dose-response analysis.






24. The use of devices - such as solar panels - to collect - focus - transport - or store solar energy.






25. This category includes organisms that consume producers (plants and algae).






26. A system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.






27. The process of burning.






28. Bacteria or fungi that absorb nutrients from nonliving organic matter like plant material - the wastes of living organisms - and corpses. They convert these materials into inorganic forms.






29. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.






30. An introduced - normative species.






31. The management of forest plantations for the purpose of harvesting timber.






32. Organisms that derive energy from consuming nonliving organic matter.






33. The finest soil - made up of particles that are less than 0.002 mm in diameter.






34. Nets that are dragged through the water and indiscriminately catch everything in their path.






35. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






36. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






37. Graphical representations of populations' ages.






38. The degree to which a substance is biologically harmful.






39. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






40. Each of the feeding levels in a food chain.






41. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






42. Organisms that are capable of interbreeding with one another and incapable of breeding with other species.






43. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.






44. A symbiotic relationship in which both species benefit.






45. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






46. The energy of motion.






47. Radioactive wastes that produce low levels of ionizing radiation.






48. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






49. A hydrocarbon that forms as sediments are buried and pressurized.






50. Land that's fit to be cultivated.
