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. Organisms that consume both producers and primary consumers.






2. The place where two plates abut each other.






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






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






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






6. A waste product produced by the burning of coal.






7. A platinum - coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust - converting them to CO2.






8. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.






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






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






11. When the majority of a building's occupants experience certain symptoms that vary with the amount of time spent in the building.






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






13. The outermost shell of the atmosphere - between the mesosphere and outer space - where temperatures increase steadily with altitude.






14. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






15. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






16. An animal that only consumes other animals.






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






18. When ecological succession begins in a virtually lifeless area - such as the area behind a moving glacier.






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






20. A symbiotic relationship in which one member is helped by the association and the other is harmed.






21. The least pure coal.






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






23. The second-purest form of coal.






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






25. The value of natural resources.






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






27. The capacity to do work.






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






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






30. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.






31. An estimate of the amount of fossil fuel that can be obtained from reserve.






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






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






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






35. A method of supplying irrigation water through tubes that literally drip water onto the soil at the base of each plant.






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






37. The edges of tectonic plates.






38. Organisms that consume primary consumers.






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






40. Pertaining to factors or things that are separate and independent from living things; nonliving.






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






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






43. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.






44. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






45. A process in which rows of crops are plowed across the hillside; this prevents the erosion that can occur when rows are cut up and down on a slope. ...






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






47. To convert or change into a vapor.






48. 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.






49. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






50. The third purest form of coal.
