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






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






3. 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






4. 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.






5. The fraction of solar energy that is reflected back into space.






6. 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.






7. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






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






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






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






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






12. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.






13. The removal of all of the trees in an area.






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






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






16. 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).






17. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






18. Any substance that has an LD50 - of 50 mg or less per kg of body weight.






19. Drilling a hole in the ground that's below the water table to hold waste.






20. Organisms in the first stages of succession.






21. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.






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






23. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






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






25. The part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life.






26. The form petroleum takes when in the ground.






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






28. The day-to-day use of environmental resources as food - clothing - and housing.






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






30. 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).






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






32. The number of live births per 1 -000 members of the population in a year.






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






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






35. A platinum - coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust - converting them to CO2.






36. The water from which a river rises; a source.






37. Devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.






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






39. A region of the ocean near the equator - characterized by calms - light winds - or squalls.






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






41. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels - especially coal.






42. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






43. Change in the genetic composition of a population during successive generations as a result of natural selection acting on the genetic variation among individuals and resulting in the development of new species.






44. Power generated using water.






45. Biotic and abiotic natural ecosystems.






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






47. Also known as transform faults - boundaries at which plates are moving past each other - sideways.






48. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






49. 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.






50. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.
