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. This category includes organisms that consume producers (plants and algae).






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






3. 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






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






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






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






7. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels.






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






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






10. When soil becomes water-logged and then dries out - and salt forms a layer on its surface.






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






12. The molten core of the Earth.






13. 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.






14. 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.






15. 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.






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






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






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






19. 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.






20. The result of a pathogen invading a body.






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






22. Resources that are often formed by very slow geologic processes - so we consider them incapable of being regenerated within the realm of human existence.






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






24. When the majority of a building's occupants experience certain symptoms that vary with the amount of time spent in the building.






25. 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.






26. Pertaining to factors or things that are separate and independent from living things; nonliving.






27. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






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






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






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






31. 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).






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






33. The day-to-day use of environmental resources as food - clothing - and housing.






34. 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.






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






36. Land that's fit to be cultivated.






37. The least pure coal.






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






39. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






40. Biotic and abiotic natural ecosystems.






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






42. A process in which rows of crops are plowed across the hillside; this prevents the erosion that can occur when rows are cut up and down on a slope. ...






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






44. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.






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






46. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






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






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






49. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






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