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






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






4. The form petroleum takes when in the ground.






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






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






7. The condition in which - at ecosystem boundaries - there is greater species diversity and biological density than there is in the heart of ecological communities.






8. 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.






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






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






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






12. A layer of soil.






13. An organism that must obtain food energy from secondary sources - for example - by eating plant or animal matter.






14. The cleanest-burning coal; almost pure carbon.






15. Biotic and abiotic natural ecosystems.






16. Land that's fit to be cultivated.






17. The least pure coal.






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






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






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






22. The movement of individuals out of a population.






23. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






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






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






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






27. The outermost shell of the atmosphere - between the mesosphere and outer space - where temperatures increase steadily with altitude.






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






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






30. 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).






31. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






32. The second-purest form of coal.






33. The movement of individuals into a population.






34. 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.






35. Living or derived from living things.






36. The practice of alternating the crops grown on a piece of land - for example - corn one year - legumes for two years - and then back to corn.






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






38. The use of devices - such as solar panels - to collect - focus - transport - or store solar energy.






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






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






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






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






43. Is equal to the number of deaths per 1 -000 members of the population in a year.






44. 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.






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






46. 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.






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






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






49. Refers to when farmers plant seeds without using a plow to turn the soil.






50. A place where a large quantity of a resource sits for a long period of time.
