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.

1. Organisms that consume primary consumers.






2. 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






3. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






4. The A layer of soil is often referred to as topsoil and is most important for plant growth.






5. The value of natural resources.






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






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






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






9. Ozone that exists in the trophosphere.






10. A soil horizon; B receives the minerals and organic materials that are leached out of the A horizon.






11. 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.






12. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






13. Sunlight.






14. A soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock - with some organic material; often referred to as topsoil.

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






23. 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.






24. 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.






25. Radioactive wastes that produce high levels of ionizing radiation.






26. A hydrocarbon that forms as sediments are buried and pressurized.






27. An estimate of the amount of fossil fuel that can be obtained from reserve.






28. 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).






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






30. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.






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






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






33. 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.

35. Land that's fit to be cultivated.






36. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






37. 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.






38. 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. ...

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






45. Any waste that poses a danger to human health; it must be dealt with in a different way from other types of waste.






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






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






48. Pollution that does not have a specific point of release - open -loop recycling -when materials are reused to form new products.






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






50. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap
