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






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






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






4. The unit used to describe the volume of fossil fuels.






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






6. An effect that results from long -term exposure to low levels of toxin.






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






8. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






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






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






11. The second-purest form of coal.






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






13. An introduced - normative species.






14. The energy of motion.






15. Any waste that poses a danger to human health; it must be dealt with in a different way from other types of waste.






16. Is the practice of planting bands of different crops across a hillside.






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






18. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






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






20. The value of natural resources.






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






22. Land that's fit to be cultivated.






23. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






24. A usually triangular alluvial deposit at the mouth of a river.






25. Involves the sinking of shafts to reach underground deposits. In this type of mining - networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal.






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






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






28. When ecological succession begins in a virtually lifeless area - such as the area behind a moving glacier.






29. 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.






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






31. 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.






32. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.






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






34. When a species occupies a smaller niche than it would in the absence of competition.






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






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






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






38. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.






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






40. The form petroleum takes when in the ground.






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






42. 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.






43. 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.






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






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






46. The practice of alternating the crops grown on a piece of land - for example - corn one year - legumes for two years - and then back to corn.






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






48. The liquid that percolates to the bottom of a landfill.






49. 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.






50. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.
