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 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.






2. 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).






3. Countries that have a renewable annual water supply of less than 1 -000 m3 per person.






4. Is the practice of planting bands of different crops across a hillside.






5. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.






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






7. Gave the EPA power to set emission standards for major sources of noise - including transportation - machinery - and construction.






8. Calculating risk - or the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen.






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






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






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






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






13. The removal of select trees in an area; this leaves the majority of the habitat in place and has less of an impact on the ecosystem.






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






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






16. Involves the sinking of shafts to reach underground deposits. In this type of mining - networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal.






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






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






20. 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.






21. 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.






22. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






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






24. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






25. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.






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






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






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






29. 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.






30. 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.






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






32. Any weathering that's caused by the activities of living organisms.






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






34. 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.






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






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






37. An introduced - normative species.






38. When water rights are given to those who have historically used the water in a certain area.






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






40. Ozone that exists in the trophosphere.






41. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






42. A usually triangular alluvial deposit at the mouth of a river.






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






44. The value of natural resources.






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






46. The edges of tectonic plates.






47. 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






48. 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.






49. A place where a large quantity of a resource sits for a long period of time.






50. 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
