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






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






3. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






4. Drilling a hole in the ground that's below the water table to hold waste.






5. 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.






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






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






8. 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.






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






10. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.






11. The value of natural resources.






12. 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






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






14. Power generated using water.






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






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






17. The energy of motion.






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






19. 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






20. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






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






22. The edges of tectonic plates.






23. The biological treatment of wastewater in order to continue to remove biodegradable waste.






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






25. Organisms that consume both producers and primary consumers.






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






27. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






28. The outermost shell of the atmosphere - between the mesosphere and outer space - where temperatures increase steadily with altitude.






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






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






31. The maintenance of a species or ecosystem in order to ensure their perpetuation - with no concern as to their potential monetary value






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






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






34. Organisms that derive energy from consuming nonliving organic matter.






35. The place where two plates abut each other.






36. 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.






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. Creating flat platforms in the hillside that provide a level planting surface - which reduces soil runoff from the slope.






39. Piles of gangue - which is the waste material that results from mining.






40. The raising of fish and other aquatic species in captivity for harvest.






41. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






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






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






44. The process of burning.






45. The area or environment where an organism or ecological community normally lives or occurs.






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






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






48. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






49. The least pure coal.






50. Living or derived from living things.
