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.

2. The degree to which a substance is biologically harmful.






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






4. The second-purest form of coal.






5. 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).






6. The form petroleum takes when in the ground.






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






8. 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






9. Graphical representations of populations' ages.






10. The least pure coal.






11. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






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






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






14. 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.






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






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






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






18. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






19. The maximum population size that can be supported by the available resources in a region.

24. Occurs when infection causes a change in the state of health.






25. Sunlight.






26. A soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock - with some organic material; often referred to as topsoil.






27. The thinning of the ozone layer over Antarctica (and to some extent - over the Arctic).






28. A complex of interrelated food chains in an ecological community.






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

42. An organism that must obtain food energy from secondary sources - for example - by eating plant or animal matter.






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






44. 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.






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






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






47. 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.

49. 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.






50. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.
