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 more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






2. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.






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






4. Acid rain - acid hail - acid snow; all of which occur as a result of pollution in the atmosphere.






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






6. To convert or change into a vapor.






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






8. Organisms that consume primary consumers.






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






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






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






12. 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.






13. 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.






14. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






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






16. 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.






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






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






19. The least pure coal.






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






21. An introduced - normative species.






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






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






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






25. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev






26. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






27. The value of natural resources.






28. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






29. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.






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






31. When one species feeds on another.






32. 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.






33. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






34. The solids that remain after the secondary treatment of sewage.






35. 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).






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






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






38. 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.






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






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






41. Being extinct or the process of becoming extinct.






42. Living or derived from living things.






43. A semiconductor device that converts the energy of sunlight into electric energy.






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






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






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






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






48. The energy of motion.






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






50. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap
