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






2. An area in which a particular mineral is concentrated - mining -the excavation of the Earth for the purpose of extracting ore or minerals.






3. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






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






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






6. 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.






7. 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.






8. The part of the mantle that lies just below the lithosphere.






9. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






10. A tank filled with aerobic bacteria that's used to treat sewage.






11. A system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.






12. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






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






14. A program funded by the federal government and a trust that's funded by taxes on chemicals; identifies pollutants and cleans up hazardous waste sites.






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






16. The industry or occupation devoted to the catching - processing - or selling of fish - shellfish - or other aquatic animals.






17. The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.






18. 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.






19. Sunlight.






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






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






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






23. Organisms in the first stages of succession.






24. 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.






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






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






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






28. The day-to-day use of environmental resources as food - clothing - and housing.






29. 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.






30. The least pure coal.






31. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






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






33. The structure obtained if we organize the amount of energy contained in producers and consumers in an ecosystem by kilocalories per square meter - from largest to smallest.






34. Energy at rest - or stored energy.






35. An opening in the Earth's crust through which molten lava - ash - and gases are ejected.






36. 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.






37. Organisms that consume both producers and primary consumers.






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






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






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






41. Formed from populations of different species occupying the same geographic area.






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






43. 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.






44. The dosage level of a toxin at which a negative effect occurs.






45. 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.






46. The value of natural resources.






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






48. A symbiotic relationship in which both species benefit.






49. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






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