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. Each of the feeding levels in a food chain.






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






3. 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.






4. A usually triangular alluvial deposit at the mouth of a river.






5. Organisms that consume primary consumers.






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






7. The gradual breakdown of rock into smaller and smaller particles - caused by natural chemical - physical - and biological factors.






8. The point at which 50 percent of the test organisms show a negative effect from a toxin.






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






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






11. 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.






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






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






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






15. When the majority of a building's occupants experience certain symptoms that vary with the amount of time spent in the building.






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






17. Poor nutrition that results from an insufficient or poorly balanced diet.






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






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






20. A layer of soil.






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






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






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






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






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






26. 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.






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






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






29. Being extinct or the process of becoming extinct.






30. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






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






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






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






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






35. States that matter can neither be created nor destroyed.






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






37. To convert or change into a vapor.






38. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.






39. The management of forest plantations for the purpose of harvesting timber.






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






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






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






43. The bedrock - which lies below all of the other layers of soil - is referred to as the R horizon.






44. Species that originate and live - or occur naturally - in an area or environment.






45. The edges of tectonic plates.






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






47. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






48. Radioactive wastes that produce low levels of ionizing radiation.






49. Living or derived from living things.






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