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






2. When the signs and symptoms of an illness can be attributed to a specific infectious organism that resides in the building.






3. The energy of motion.






4. Energy at rest - or stored energy.






5. This category includes organisms that consume producers (plants and algae).






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






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






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






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






10. Organisms that consume both producers and primary consumers.






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






12. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






13. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






14. When the energy released from waste incineration is used to generate electricity.






15. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.






16. Areas where cutting has occurred and a new - younger forest has arisen.






17. 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.






18. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






19. When water rights are given to those who have historically used the water in a certain area.






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






21. A tank filled with aerobic bacteria that's used to treat sewage.






22. The liquid that percolates to the bottom of a landfill.






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






24. 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.






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






26. Any substance than is inhaled - ingested - or absorbed at dosages sufficient to damage a living organism.






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






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






29. The maximum population size that can be supported by the available resources in a region.






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






31. Any other species of fish - mammals - or birds that are caught that are not the target organism.






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






33. A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and - in turn - is preyed upon by a higher member.






34. Using strategies to reduce the amount of risk (the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen).






35. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.






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






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






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






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






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






41. 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.






42. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






43. To convert or change into a vapor.






44. 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.






45. 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.






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






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






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






49. Organisms that are capable of interbreeding with one another and incapable of breeding with other species.






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