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. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.






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






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






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






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






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






7. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






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






9. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






10. 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).






11. 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.






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






13. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






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






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






16. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






17. Biotic and abiotic natural ecosystems.






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






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






20. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.






21. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.






22. The carrier organism through which pathogens can attack.






23. Is equal to the number of deaths per 1 -000 members of the population in a year.






24. The energy of motion.






25. The act or process of transpiring - or releasing water vapor - especially through the stomata of plant tissue or the pores of the skin.






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






27. Graphical representations of populations' ages.






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






29. 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






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






31. A process in which rows of crops are plowed across the hillside; this prevents the erosion that can occur when rows are cut up and down on a slope. ...






32. The place where two plates abut each other.






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






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






35. The unit used to describe the volume of fossil fuels.






36. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






37. To convert or change into a vapor.






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






39. Involves the sinking of shafts to reach underground deposits. In this type of mining - networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal.






40. The removal of select trees in an area; this leaves the majority of the habitat in place and has less of an impact on the ecosystem.






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






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






43. 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.






44. Pertaining to factors or things that are separate and independent from living things; nonliving.






45. The least pure coal.






46. 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.






47. Resources that are often formed by very slow geologic processes - so we consider them incapable of being regenerated within the realm of human existence.






48. The industry or occupation devoted to the catching - processing - or selling of fish - shellfish - or other aquatic animals.






49. The number of live births per 1 -000 members of the population in a year.






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