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 degree to which a substance is biologically harmful.






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






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






4. Land that's fit to be cultivated.






5. 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.






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






7. Piles of gangue - which is the waste material that results from mining.






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






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






10. Species that originate and live - or occur naturally - in an area or environment.






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






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






13. 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.






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






15. The process that occurs when two different species in a region compete and the better adapted species wins.






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






17. Organisms that consume primary consumers.






18. A plate boundary at which plates are moving away from each other. This causes an upwelling of magma from the mantle to cool and form new crust.






19. An area in which a particular mineral is concentrated - mining -the excavation of the Earth for the purpose of extracting ore or minerals.






20. The carrier organism through which pathogens can attack.






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






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






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






24. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






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






26. 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.






27. Organisms that consume secondary consumers or other tertiary consumers.






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






29. A group of organisms of the same species that live in the same area.






30. When a species occupies a smaller niche than it would in the absence of competition.






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






32. The process of burning.






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






34. An intensification of the Greenhouse Effect due to the increased presence of heat-trapping gases in the atmosphere.






35. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






36. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






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






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






39. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.






40. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






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






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






43. To convert or change into a vapor.






44. Transition in species composition of a biological community - often following ecological disturbance of the community; the establishment of a biological community in any area virtually barren of life.






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






46. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






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






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






49. The maintenance of a species or ecosystem in order to ensure their perpetuation - with no concern as to their potential monetary value






50. The process of fusing two nuclei.
