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






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






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






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






5. Fires that typically burn only the forest's underbrush and do little damage to mature trees. Surface fires actually serve to protect the forest from more harmful fires by removing underbrush and dead materials that would burn quickly and at high temp






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






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






8. The movement of individuals into a population.






9. 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.






10. 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.






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






13. The finest soil - made up of particles that are less than 0.002 mm in diameter.






14. A symbiotic relationship in which both species benefit.






15. 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.






16. 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.






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






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






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






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






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






22. The unit used to describe the volume of fossil fuels.






23. Bacteria or fungi that absorb nutrients from nonliving organic matter like plant material - the wastes of living organisms - and corpses. They convert these materials into inorganic forms.






24. Energy at rest - or stored energy.






25. The carrier organism through which pathogens can attack.






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






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






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






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






30. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap






31. The energy of motion.






32. A long - relatively narrow island running parallel to the mainland-built up by the action of waves and currents and serving to protect the coast from erosion by surf and tidal surges.






33. The fraction of solar energy that is reflected back into space.






34. Organisms in the first stages of succession.






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






36. 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.






37. 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.






38. 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.






39. An animal that only consumes other animals.






40. Living or derived from living things.






41. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






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






43. A waste product produced by the burning of coal.






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






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






46. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






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






48. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.






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






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