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 part of the wide lower course of a river where its current is met by the tides.






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






3. The vertical movement of a mass of matter due to heating and cooling; this can happen in both the atmosphere and Earth's mantle.






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






5. The molten core of the Earth.






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






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






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






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






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






11. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.






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






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






14. The removal of trees for agricultural purposes or purposes of exportation.






15. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






16. 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






17. A symbiotic relationship in which both species benefit.






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






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






20. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






21. Non-moving sources of pollution - such as factories.






22. The structure obtained if we organize the amount of energy contained in producers and consumers in an ecosystem by kilocalories per square meter - from largest to smallest.






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






24. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






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






26. The amount that the population would grow if there were unlimited resources in its environment.






27. A waste product produced by the burning of coal.






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






29. The amount of energy that plants pass on to the community of herbivores in an ecosystem.






30. An influential theory that concerns the long - term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






31. A plate boundary at which plates are moving away from each other. This causes an upwelling of magma from the mantle to cool and form new crust.






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






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






34. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






35. Organisms in the first stages of succession.






36. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






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






38. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.






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






41. The process of burning.






42. To convert or change into a vapor.






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






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






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






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






47. The form petroleum takes when in the ground.






48. The value of natural resources.






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






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