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. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.






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






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






4. A group of modern windmills.






5. Biotic and abiotic natural ecosystems.






6. Any substance that has an LD50 - of 50 mg or less per kg of body weight.






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






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






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






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






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






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






13. Power generated using water.






14. A layer of soil.






15. Being extinct or the process of becoming extinct.






16. The layer of the Earth between the crust and the core.






17. 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






18. 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.






19. 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.






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






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






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






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






24. Any noise that causes stress or has the potential to damage human health.






25. The amount of energy that plants pass on to the community of herbivores in an ecosystem.






26. 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.






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






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






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






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






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






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






33. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






34. Organisms that consume both producers and primary consumers.






35. The second-purest form of coal.






36. The biological treatment of wastewater in order to continue to remove biodegradable waste.






37. 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






38. 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.






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






40. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.






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






42. 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.






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






44. The gradual breakdown of rock into smaller and smaller particles - caused by natural chemical - physical - and biological factors.






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






46. Land that's fit to be cultivated.






47. Sunlight.






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






49. Any other species of fish - mammals - or birds that are caught that are not the target organism.






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