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 movement of individuals out of a population.






2. Areas where cutting has occurred and a new - younger forest has arisen.






3. A method of supplying irrigation water through tubes that literally drip water onto the soil at the base of each plant.






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






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






6. Organisms in the first stages of succession.






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






8. 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.






9. Biotic and abiotic natural ecosystems.






10. 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.






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






12. Soil composed of a mixture of sand - clay - silt - and organic matter.






13. The dosage level of a toxin at which a negative effect occurs.






14. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






15. A platinum - coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust - converting them to CO2.






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






17. 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.






18. Being extinct or the process of becoming extinct.






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






20. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener






21. 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.






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






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






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






25. An area in which a particular mineral is concentrated - mining -the excavation of the Earth for the purpose of extracting ore or minerals.






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






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






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






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






30. Organisms that consume primary consumers.






31. Organisms that consume secondary consumers or other tertiary consumers.






32. Countries that have a renewable annual water supply of less than 1 -000 m3 per person.






33. 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).






34. A plate boundary where two plates are moving toward each other.






35. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






36. Says that energy can neither be created nor destroyed; it can only be transferred and transformed.






37. 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.






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






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






40. The result of a pathogen invading a body.






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






42. An animal that only consumes other animals.






43. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






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






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






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






47. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






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






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






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