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. An animal that only consumes other animals.






2. Formed from populations of different species occupying the same geographic area.






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






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






5. Living or derived from living things.






6. 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.






7. A group of modern windmills.






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






9. To convert or change into a vapor.






10. The thinning of the ozone layer over Antarctica (and to some extent - over the Arctic).






11. 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.






12. Each of the feeding levels in a food chain.






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






14. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.






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






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






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






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






19. Energy at rest - or stored energy.






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






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






22. The process in which plants absorb ammonium (NH3) - ammonia ions (NH4+) - and nitrate ions (NO3) through their roots.






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






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






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






26. Being extinct or the process of becoming extinct.






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






28. Radioactive wastes that produce high levels of ionizing radiation.






29. 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.






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






31. 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.






32. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






33. The process of fusing two nuclei.






34. When soil becomes water-logged and then dries out - and salt forms a layer on its surface.






35. An organism such as a bacterium or protozoan - that obtains its nourishment through the oxidation of inorganic chemical compounds - as opposed to photosynthesis.






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






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






38. Graphical representations of populations' ages.






39. Also known as transform faults - boundaries at which plates are moving past each other - sideways.






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






41. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






42. The number of children a couple must have in order to replace themselves in a population.






43. Transition in species composition of a biological community - often following ecological disturbance of the community; the establishment of a biological community in any area virtually barren of life.






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






45. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.






46. 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.






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






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






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






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