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. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






2. The place where two plates abut each other.






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






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






5. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.






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






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






8. 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).






9. Is equal to the number of deaths per 1 -000 members of the population in a year.






10. The carrier organism through which pathogens can attack.






11. The least pure coal.






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






13. 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.






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






15. The second-purest form of coal.






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






17. Organisms that consume primary consumers.






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






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






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






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






22. 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.






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






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. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






27. 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.






28. Any waste that poses a danger to human health; it must be dealt with in a different way from other types of waste.






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






30. 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






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






32. Pollutants that are released directly into the lower atmosphere.






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






34. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






35. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.






36. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






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






38. 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






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






40. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.






41. 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.






42. The amount of energy that plants pass on to the community of herbivores in an ecosystem.






43. 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.






44. The practice of alternating the crops grown on a piece of land - for example - corn one year - legumes for two years - and then back to corn.






45. 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






46. The vertical movement of a mass of matter due to heating and cooling; this can happen in both the atmosphere and Earth's mantle.






47. 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.






48. 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.






49. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






50. The A layer of soil is often referred to as topsoil and is most important for plant growth.
