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






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






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






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






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






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






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






8. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






9. An introduced - normative species.






10. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






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






12. 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.






13. Power generated using water.






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






15. A fiscal policy that lowers taxes on income - including wages and profit - and raises taxes on consumption - particularly the unsustainable consumption of non-renewable resources.






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






17. 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.






18. A tank filled with aerobic bacteria that's used to treat sewage.






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






20. Nets that are dragged through the water and indiscriminately catch everything in their path.






21. When one species feeds on another.






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






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






24. The movement of individuals out of a population.






25. The number of children a couple must have in order to replace themselves in a population.






26. Radioactive wastes that produce high levels of ionizing radiation.






27. A group of modern windmills.






28. The second-purest form of coal.






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






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






31. 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.






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






33. 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.






34. Countries that have a renewable annual water supply of about 1 -000 -2 -000 m3 per person.






35. Being extinct or the process of becoming extinct.






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






37. Each of the feeding levels in a food chain.






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






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






40. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






41. 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






42. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






43. 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.






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






45. The structure obtained if we organize the amount of energy contained in producers and consumers in an ecosystem by kilocalories per square meter - from largest to smallest.






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






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






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






49. 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.






50. The result of a pathogen invading a body.
