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 capacity to do work.






2. 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.






3. The value of natural resources.






4. The gradual breakdown of rock into smaller and smaller particles - caused by natural chemical - physical - and biological factors.






5. 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.






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






7. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






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






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






10. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






11. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






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






13. Devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.






14. The carrier organism through which pathogens can attack.






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






16. When the energy released from waste incineration is used to generate electricity.






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






18. The liquid that percolates to the bottom of a landfill.






19. Organisms that consume both producers and primary consumers.






20. An influential theory that concerns the long-term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






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






22. A tank filled with aerobic bacteria that's used to treat sewage.






23. The biological treatment of wastewater in order to continue to remove biodegradable waste.






24. Bacteria - virus - or other microorganisms that can cause disease.






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






26. 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.






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






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






29. Countries that have a renewable annual water supply of less than 1 -000 m3 per person.






30. Biotic and abiotic natural ecosystems.






31. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






32. Any substance that has an LD50 - of 50 mg or less per kg of body weight.






33. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.






34. An organism such as a bacterium or protozoan - that obtains its nourishment through the oxidation of inorganic chemical compounds - as opposed to photosynthesis.






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






36. The cleanest-burning coal; almost pure carbon.






37. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






38. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.






39. Non-moving sources of pollution - such as factories.






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






41. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






42. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.






43. Graphical representations of populations' ages.






44. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.






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






46. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






47. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






48. Sunlight.






49. Occurs when infection causes a change in the state of health.






50. Energy at rest - or stored energy.
