Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The molten core of the Earth.






2. The result of a pathogen invading a body.






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






4. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






5. A group of modern windmills.






6. The third purest form of coal.






7. The number of children a couple must have in order to replace themselves in a population.






8. Any weathering that's caused by the activities of living organisms.






9. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






10. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






11. The effect caused by a short exposure to a high level of toxin.






12. Also known as transform faults - boundaries at which plates are moving past each other - sideways.






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






14. Radioactive wastes that produce high levels of ionizing radiation.






15. The maximum population size that can be supported by the available resources in a region.






16. Organisms in the first stages of succession.






17. Energy at rest - or stored energy.






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






19. The carrier organism through which pathogens can attack.






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






21. The region draining into river system or other body of water.






22. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.






23. Soil with particles 0.002 -0.05 mm in diameter.






24. Graphical representations of populations' ages.






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






26. The point at which 50 percent of the test organisms die from a toxin.






27. The act or process of transpiring - or releasing water vapor - especially through the stomata of plant tissue or the pores of the skin.






28. The part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life.






29. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.






30. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






31. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






32. An estimate of the amount of fossil fuel that can be obtained from reserve.






33. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






34. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






35. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.






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






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






38. To convert or change into a vapor.






39. One that has never been cut; these forests have not been seriously disturbed for several hundred years.






40. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.






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






42. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






43. Ozone that exists in the trophosphere.






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






45. 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.






46. The solids that remain after the secondary treatment of sewage.






47. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






48. Any noise that causes stress or has the potential to damage human health.






49. The fraction of solar energy that is reflected back into space.






50. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.
