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 species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






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






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






4. The result of graphing a dose-response analysis.






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






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






7. Is equal to the number of deaths per 1 -000 members of the population in a year.






8. The process that occurs when two different species in a region compete and the better adapted species wins.






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






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






11. A complex of interrelated food chains in an ecological community.






12. Organisms that consume primary consumers.






13. The region draining into river system or other body of water.






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






15. Pollution that does not have a specific point of release - open -loop recycling -when materials are reused to form new products.






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






17. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels - especially coal.






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






19. 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.






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






21. When one species feeds on another.






22. Organisms that derive energy from consuming nonliving organic matter.






23. 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






24. The gaseous mass or envelope surrounding a celestial body - especially the one surrounding the Earth - which is retained by the celestial body's gravitational field.






25. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






26. 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).






27. The energy of motion.






28. The part of the mantle that lies just below the lithosphere.






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






30. Piles of gangue - which is the waste material that results from mining.






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






32. 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.






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






34. The capacity to do work.






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






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






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






38. 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.






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






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






41. Land that's fit to be cultivated.






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






43. The carrier organism through which pathogens can attack.






44. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






45. Sunlight.






46. The value of natural resources.






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






48. The act or process of transpiring - or releasing water vapor - especially through the stomata of plant tissue or the pores of the skin.






49. An introduced - normative species.






50. The second-purest form of coal.
