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. Being extinct or the process of becoming extinct.






2. Creating flat platforms in the hillside that provide a level planting surface - which reduces soil runoff from the slope.






3. 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.






4. States that matter can neither be created nor destroyed.






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






6. Gave the EPA power to set emission standards for major sources of noise - including transportation - machinery - and construction.






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






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






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






10. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.






11. 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.






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






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






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






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






16. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.






17. When a species occupies a smaller niche than it would in the absence of competition.






18. The number of live births per 1 -000 members of the population in a year.






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






20. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






21. 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.






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






23. The carrier organism through which pathogens can attack.






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






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






26. Biotic and abiotic natural ecosystems.






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






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






29. A plate boundary where two plates are moving toward each other.






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






31. A group of organisms of the same species that live in the same area.






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






33. A symbiotic relationship in which both species benefit.






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






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






36. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.






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






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






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






40. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






41. Non-moving sources of pollution - such as factories.






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






43. The value of natural resources.






44. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






45. The area or environment where an organism or ecological community normally lives or occurs.






46. 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.






47. 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. ...






48. The raising of fish and other aquatic species in captivity for harvest.






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






50. 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.
