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. Any other species of fish - mammals - or birds that are caught that are not the target organism.






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






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






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






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






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






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






8. Resources that are often formed by very slow geologic processes - so we consider them incapable of being regenerated within the realm of human existence.






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






10. Soil composed of a mixture of sand - clay - silt - and organic matter.






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






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






13. The least pure coal.






14. The unit used to describe the volume of fossil fuels.






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






16. Areas where cutting has occurred and a new - younger forest has arisen.






17. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






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






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






20. A layer of soil.






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






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






23. 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






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






25. The part of the wide lower course of a river where its current is met by the tides.






26. Countries that have a renewable annual water supply of about 1 -000 -2 -000 m3 per person.






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






28. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels - especially coal.






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






30. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






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






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






33. The value of natural resources.






34. The third purest form of coal.






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






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






37. When grass is consumed by animals at a faster rate than it can regrow.






38. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






39. 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.






40. Says that energy can neither be created nor destroyed; it can only be transferred and transformed.






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






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






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






44. Living or derived from living things.






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






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






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

49. Nets that are dragged through the water and indiscriminately catch everything in their path.






50. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.
