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






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






4. 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.






5. The result of a pathogen invading a body.






6. 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).






7. Energy at rest - or stored energy.






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






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






10. 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.






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






12. A group of modern windmills.






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






14. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






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






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






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






18. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.






19. A plate boundary at which plates are moving away from each other. This causes an upwelling of magma from the mantle to cool and form new crust.






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






21. Poor nutrition that results from an insufficient or poorly balanced diet.






22. A layer of soil.






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






24. A region of the ocean near the equator - characterized by calms - light winds - or squalls.






25. Graphical representations of populations' ages.






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






27. 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.






28. Organisms that consume both producers and primary consumers.






29. The carrier organism through which pathogens can attack.






30. The movement of individuals out of a population.






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






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






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






34. One that has never been cut; these forests have not been seriously disturbed for several hundred years.






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






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






37. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






38. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






39. When one species feeds on another.






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






41. Radioactive wastes that produce low levels of ionizing radiation.






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






43. 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.






44. 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.






45. 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.






46. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






47. 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.






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






49. 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.






50. The A layer of soil is often referred to as topsoil and is most important for plant growth.
