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






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






3. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






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






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






6. The movement of individuals into a population.






7. Nets that are dragged through the water and indiscriminately catch everything in their path.






8. Open or forested areas built at the outer edge of a city.






9. Biotic and abiotic natural ecosystems.






10. The gaseous mass or envelope surrounding a celestial body - especially the one surrounding the Earth - which is retained by the celestial body's gravitational field.






11. Occurs when infection causes a change in the state of health.






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






13. Pollutants that are released directly into the lower atmosphere.






14. 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.






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






16. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






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






18. 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






19. 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.






20. The energy of motion.






21. An animal that only consumes other animals.






22. 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.






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






24. 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.






25. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






26. The solids that remain after the secondary treatment of sewage.






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






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






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






30. The amount that the population would grow if there were unlimited resources in its environment.






31. The least pure coal.






32. 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).






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






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






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






36. Organisms that consume both producers and primary consumers.






37. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.






38. The molten core of the Earth.






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






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






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






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






43. Graphical representations of populations' ages.






44. Living or derived from living things.






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






46. 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






47. 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.






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






49. The second-purest form of coal.






50. To convert or change into a vapor.
