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. An introduced - normative species.






2. The third purest form of coal.






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






4. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.






5. Soil with particles 0.002 -0.05 mm in diameter.






6. 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.






7. The total sum of a species' use of the biotic and abiotic resources in its environment.






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






9. Land that's fit to be cultivated.






10. Organisms in the first stages of succession.






11. The phenomenon whereby the Earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through - but absorb heat radiated back fr






12. 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.






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






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






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






16. The amount of time it takes for half of a radioactive sample to disappear.






17. 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.






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






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






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






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






22. 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.






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






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






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






26. Living or derived from living things.






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






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






29. The place where two plates abut each other.






30. 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.






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






32. 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.






33. The energy of motion.






34. 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.






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






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






37. 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.






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






39. The capacity to do work.






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






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






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






43. Ozone that exists in the trophosphere.






44. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.






45. A layer of soil.






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






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






48. When a species occupies a smaller niche than it would in the absence of competition.






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






50. To convert or change into a vapor.
