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. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






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






3. Sunlight.






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






5. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






6. A layer of soil.






7. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.






8. An estimate of the amount of fossil fuel that can be obtained from reserve.






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






10. The outer part of the Earth - consisting of the crust and upper mantle - approximately 100 km (62 miles) thick.






11. An organism that must obtain food energy from secondary sources - for example - by eating plant or animal matter.






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






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






14. Refers to when farmers plant seeds without using a plow to turn the soil.






15. The result of chemical interaction with the bedrock that is typical of the action of both water and atmospheric gases.






16. The molten core of the Earth.






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






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






19. Organisms that consume primary consumers.






20. 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.






21. The effect caused by a short exposure to a high level of toxin.






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






23. 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).






24. Bacteria or fungi that absorb nutrients from nonliving organic matter like plant material - the wastes of living organisms - and corpses. They convert these materials into inorganic forms.






25. The place where two plates abut each other.






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






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






28. 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.






29. Soil with particles 0.002 -0.05 mm in diameter.






30. States that matter can neither be created nor destroyed.






31. 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.






32. The amount of time it takes for half of a radioactive sample to disappear.






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






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






35. Living or derived from living things.






36. A symbiotic relationship in which one member is helped by the association and the other is harmed.






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






38. 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.






39. 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.






40. 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.






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






42. 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.






43. Open or forested areas built at the outer edge of a city.






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






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






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






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






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






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






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