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. Pollutants that are released directly into the lower atmosphere.






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






3. The form petroleum takes when in the ground.






4. The water from which a river rises; a source.






5. Living or derived from living things.






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






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 nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener






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






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






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






12. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.






13. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.






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






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






16. 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.






17. 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. ...






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






19. 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.






20. Poor nutrition that results from an insufficient or poorly balanced diet.






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






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






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






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






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






26. The biological treatment of wastewater in order to continue to remove biodegradable waste.






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






28. 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.






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






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






31. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






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






33. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






34. 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.






35. 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.






36. 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.






37. The use of building materials - building placement - and design to passively collect solar energy that can be used to keep a building warm or cool.






38. The number of individuals of a population that inhabit a certain unit of land or water area.






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






40. 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.






41. A semiconductor device that converts the energy of sunlight into electric energy.






42. 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).






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






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






45. Any noise that causes stress or has the potential to damage human health.






46. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.






47. The molten core of the Earth.






48. The capacity to do work.






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






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