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. A symbiotic relationship in which both species benefit.






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






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






4. A plate boundary where two plates are moving toward each other.






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






6. The place where two plates abut each other.






7. The movement of individuals into a population.






8. The second-purest form of coal.






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






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






11. A layer of soil.






12. Soil composed of a mixture of sand - clay - silt - and organic matter.






13. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






14. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.






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






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






17. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






18. Change in the genetic composition of a population during successive generations as a result of natural selection acting on the genetic variation among individuals and resulting in the development of new species.






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






20. An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.






21. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.






22. When one species feeds on another.






23. 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






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






25. Organisms that consume both producers and primary consumers.






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






27. The point at which 50 percent of the test organisms show a negative effect from a toxin.






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






29. Organisms that are capable of interbreeding with one another and incapable of breeding with other species.






30. Bacteria - virus - or other microorganisms that can cause disease.






31. 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






32. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






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






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






35. The cleanest-burning coal; almost pure carbon.






36. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev






37. Any compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






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






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






40. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






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






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






43. 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.






44. When grass is consumed by animals at a faster rate than it can regrow.






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






46. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






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






48. The management of forest plantations for the purpose of harvesting timber.






49. 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.






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