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. The area or environment where an organism or ecological community normally lives or occurs.






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






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






4. A platinum - coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust - converting them to CO2.






5. The result of a pathogen invading a body.






6. An animal that only consumes other animals.






7. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






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






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






10. An influential theory that concerns the long-term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






11. The condition in which - at ecosystem boundaries - there is greater species diversity and biological density than there is in the heart of ecological communities.






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






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






14. Open or forested areas built at the outer edge of a city.






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






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






17. The least pure coal.






18. The movement of individuals into a population.






19. 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.






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






21. 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.






22. The third purest form of coal.






23. Land that's fit to be cultivated.






24. Pollutants that are formed by the combination of primary pollutants in the atmosphere.






25. The number of individuals of a population that inhabit a certain unit of land or water area.






26. The value of natural resources.






27. 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.






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






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






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






31. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






32. The process of fusing two nuclei.






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






34. Sunlight.






35. The capacity to do work.






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






37. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.






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






39. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






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






41. A group of organisms of the same species that live in the same area.






42. The process by which the concentration of toxic substances increases in each successive link in the food chain.






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






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






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






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






47. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






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






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






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