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. Ozone that exists in the trophosphere.






2. The layer of the Earth between the crust and the core.






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






4. 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.






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






6. 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.






7. Pollutants that are formed by the combination of primary pollutants in the atmosphere.






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






9. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.






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






11. The second-purest form of coal.






12. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.






13. The condition in which - at ecosystem boundaries - there is greater species diversity and biological density than there is in the heart of ecological communities.






14. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






15. A plate boundary where two plates are moving toward each other.






16. 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.






17. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






18. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






19. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






20. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






21. 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.






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






23. The process of fusing two nuclei.






24. The total sum of a species' use of the biotic and abiotic resources in its environment.






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






26. Graphical representations of populations' ages.






27. The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.






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






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






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






31. When the signs and symptoms of an illness can be attributed to a specific infectious organism that resides in the building.






32. Biotic and abiotic natural ecosystems.






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






34. When water rights are given to those who have historically used the water in a certain area.






35. The movement of individuals out of a population.






36. To convert or change into a vapor.






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






38. The carrier organism through which pathogens can attack.






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






40. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






41. The process of soil particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrades the soil to a coarser - sandier - stonier texture.






42. Any substance than is inhaled - ingested - or absorbed at dosages sufficient to damage a living organism.






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






44. The number of live births per 1 -000 members of the population in a year.






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






46. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.






47. 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.






48. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.






49. The raising of fish and other aquatic species in captivity for harvest.






50. 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.
