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. Organisms that consume both producers and primary consumers.






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






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






4. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






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






6. The process of soil particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrades the soil to a coarser - sandier - stonier texture.






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






8. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.






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






10. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






11. The edges of tectonic plates.






12. 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.






13. When one species feeds on another.






14. An introduced - normative species.






15. The capacity to do work.






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






17. Organisms in the first stages of succession.






18. When ecological succession begins in a virtually lifeless area - such as the area behind a moving glacier.






19. Open or forested areas built at the outer edge of a city.






20. 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.






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






22. To convert or change into a vapor.






23. Radioactive wastes that produce low levels of ionizing radiation.






24. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






25. Any process that breaks rock down into smaller pieces without changing the chemistry of the rock; typically wind and water.






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






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






28. Refers to when farmers plant seeds without using a plow to turn the soil.






29. Each of the feeding levels in a food chain.






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






31. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






32. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






33. 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.






34. When an area of vegetation is cut down and burned before being planted with crops.






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






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. The movement of individuals out of a population.






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






39. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






40. The result of a pathogen invading a body.






41. Ozone that exists in the trophosphere.






42. A soil horizon; B receives the minerals and organic materials that are leached out of the A horizon.






43. The process of burning.






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






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






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






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






48. The energy of motion.






49. 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.






50. An animal that only consumes other animals.
