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






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






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






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






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






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






7. Piles of gangue - which is the waste material that results from mining.






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






9. The carrier organism through which pathogens can attack.






10. An introduced - normative species.






11. Also known as transform faults - boundaries at which plates are moving past each other - sideways.






12. An effect that results from long -term exposure to low levels of toxin.






13. Any substance than is inhaled - ingested - or absorbed at dosages sufficient to damage a living organism.






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






15. 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).






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






17. 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.






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






19. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.






20. The outer part of the Earth - consisting of the crust and upper mantle - approximately 100 km (62 miles) thick.






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






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






23. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.






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






25. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.






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






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






28. 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






29. 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.






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






31. 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.






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






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






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






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






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






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






38. Countries that have a renewable annual water supply of about 1 -000 -2 -000 m3 per person.






39. The region draining into river system or other body of water.






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






41. The practice of alternating the crops grown on a piece of land - for example - corn one year - legumes for two years - and then back to corn.






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






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






44. The value of natural resources.






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






46. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.






47. The process in which plants absorb ammonium (NH3) - ammonia ions (NH4+) - and nitrate ions (NO3) through their roots.






48. 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.






49. Energy at rest - or stored energy.






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