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. Pollution that does not have a specific point of release - open -loop recycling -when materials are reused to form new products.






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






3. The edges of tectonic plates.






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






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






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






7. Using strategies to reduce the amount of risk (the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen).






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






9. 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.






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






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






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






13. Organisms that consume primary consumers.






14. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.






15. The place where two plates abut each other.






16. A usually triangular alluvial deposit at the mouth of a river.






17. The amount that the population would grow if there were unlimited resources in its environment.






18. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






19. Organisms in the first stages of succession.






20. Sunlight.






21. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev






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






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






24. The removal of trees for agricultural purposes or purposes of exportation.






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






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






27. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.






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






29. Drilling a hole in the ground that's below the water table to hold waste.






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






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






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






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






34. Fires that typically burn only the forest's underbrush and do little damage to mature trees. Surface fires actually serve to protect the forest from more harmful fires by removing underbrush and dead materials that would burn quickly and at high temp






35. The movement of individuals into a population.






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






37. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap






38. The result of a pathogen invading a body.






39. The capacity to do work.






40. 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.






41. 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.






42. Graphical representations of populations' ages.






43. 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.






44. 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.






45. Formed from populations of different species occupying the same geographic area.






46. The bedrock - which lies below all of the other layers of soil - is referred to as the R horizon.






47. Creating flat platforms in the hillside that provide a level planting surface - which reduces soil runoff from the slope.






48. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels.






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






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