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. The process by which the concentration of toxic substances increases in each successive link in the food chain.






2. A group of modern windmills.






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






4. The amount of time it takes for half of a radioactive sample to disappear.






5. The process that occurs when two different species in a region compete and the better adapted species wins.






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






7. 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






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






9. Acid rain - acid hail - acid snow; all of which occur as a result of pollution in the atmosphere.






10. Transition in species composition of a biological community - often following ecological disturbance of the community; the establishment of a biological community in any area virtually barren of life.






11. 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.






12. A layer of soil.






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






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






15. 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.






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






17. 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.






18. 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.






19. Radioactive wastes that produce high levels of ionizing radiation.






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






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






22. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






23. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






24. 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.






25. The effect caused by a short exposure to a high level of toxin.






26. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






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






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






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






30. The total sum of a species' use of the biotic and abiotic resources in its environment.






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






32. An intensification of the Greenhouse Effect due to the increased presence of heat-trapping gases in the atmosphere.






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






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






35. The removal of all of the trees in an area.






36. The least pure coal.






37. 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.






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






39. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






40. The place where two plates abut each other.






41. Energy at rest - or stored 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. 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.






44. When the energy released from waste incineration is used to generate electricity.






45. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






46. 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.






47. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






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






49. When the signs and symptoms of an illness can be attributed to a specific infectious organism that resides in the building.






50. 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
