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. The result of a pathogen invading a body.






2. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.






3. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






4. The edges of tectonic plates.






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






6. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






7. 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).






8. The use of building materials - building placement - and design to passively collect solar energy that can be used to keep a building warm or cool.






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






10. Power generated using water.






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






12. The structure obtained if we organize the amount of energy contained in producers and consumers in an ecosystem by kilocalories per square meter - from largest to smallest.






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






14. Organisms that derive energy from consuming nonliving organic matter.






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






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






17. Any noise that causes stress or has the potential to damage human health.






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






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






20. Non-moving sources of pollution - such as factories.






21. 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.






22. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.






23. The part of the wide lower course of a river where its current is met by the tides.






24. 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.






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






26. The carrier organism through which pathogens can attack.






27. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






28. The effect caused by a short exposure to a high level of toxin.






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






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






31. A fiscal policy that lowers taxes on income - including wages and profit - and raises taxes on consumption - particularly the unsustainable consumption of non-renewable resources.






32. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.






33. Organisms that consume secondary consumers or other tertiary consumers.






34. The part of the mantle that lies just below the lithosphere.






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






36. An effect that results from long -term exposure to low levels of toxin.






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






38. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






39. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.






40. Graphical representations of populations' ages.






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






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






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






44. The maintenance of a species or ecosystem in order to ensure their perpetuation - with no concern as to their potential monetary value






45. The third purest form of coal.






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






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






48. When one species feeds on another.






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






50. 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
