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. 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






2. When the signs and symptoms of an illness can be attributed to a specific infectious organism that resides in the building.






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






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






5. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






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






7. 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).






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






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






10. The outer part of the Earth - consisting of the crust and upper mantle - approximately 100 km (62 miles) thick.






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






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






14. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






15. 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.






16. Involves the sinking of shafts to reach underground deposits. In this type of mining - networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal.






17. 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.






18. Living or derived from living things.






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






20. An introduced - normative species.






21. Species that originate and live - or occur naturally - in an area or environment.






22. When soil becomes water-logged and then dries out - and salt forms a layer on its surface.






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






24. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






25. The dosage level of a toxin at which a negative effect occurs.






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






27. One that has never been cut; these forests have not been seriously disturbed for several hundred years.






28. The liquid that percolates to the bottom of a landfill.






29. An organism such as a bacterium or protozoan - that obtains its nourishment through the oxidation of inorganic chemical compounds - as opposed to photosynthesis.






30. Sunlight.






31. A usually triangular alluvial deposit at the mouth of a river.






32. 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.






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






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






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






36. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.






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






38. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.






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






40. Says that energy can neither be created nor destroyed; it can only be transferred and transformed.






41. 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.






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






43. The vertical movement of a mass of matter due to heating and cooling; this can happen in both the atmosphere and Earth's mantle.






44. Countries that have a renewable annual water supply of about 1 -000 -2 -000 m3 per person.






45. The layer of the Earth between the crust and the core.






46. 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.






47. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






48. The molten core of the Earth.






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






50. A system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.
