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. Countries that have a renewable annual water supply of about 1 -000 -2 -000 m3 per person.






2. 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).






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






4. 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.






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






6. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






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






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






9. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






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






11. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






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






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






14. The process of fusing two nuclei.






15. Any process that breaks rock down into smaller pieces without changing the chemistry of the rock; typically wind and water.






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






17. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






18. 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.






19. 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.






20. 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.






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






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






23. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.






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






25. When one species feeds on another.






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






27. An intensification of the Greenhouse Effect due to the increased presence of heat-trapping gases in the atmosphere.






28. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






29. A symbiotic relationship in which both species benefit.






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






31. Any compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






32. An animal that only consumes other animals.






33. The finest soil - made up of particles that are less than 0.002 mm in diameter.






34. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






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






36. 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.






37. Pollutants that are formed by the combination of primary pollutants in the atmosphere.






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






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






40. Land that's fit to be cultivated.






41. A group of organisms of the same species that live in the same area.






42. 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






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






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






45. 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).






46. 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.






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






48. 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.






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






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