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. Organisms that consume primary consumers.






2. Is equal to the number of deaths per 1 -000 members of the population in a year.






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






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






5. 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.






6. The value of natural resources.






7. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






8. An opening in the Earth's crust through which molten lava - ash - and gases are ejected.






9. 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).






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






11. A soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock - with some organic material; often referred to as topsoil.






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






13. The removal of select trees in an area; this leaves the majority of the habitat in place and has less of an impact on the ecosystem.






14. The amount of energy that plants pass on to the community of herbivores in an ecosystem.






15. Pertaining to factors or things that are separate and independent from living things; nonliving.






16. 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.






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






18. The molten core of the Earth.






19. Any waste that poses a danger to human health; it must be dealt with in a different way from other types of waste.






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






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






22. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






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






24. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






25. The carrier organism through which pathogens can attack.






26. When one species feeds on another.






27. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






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






29. 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.






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






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






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






33. Creating flat platforms in the hillside that provide a level planting surface - which reduces soil runoff from the slope.






34. 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.






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






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






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






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






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






40. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






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






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






43. A complex of interrelated food chains in an ecological community.






44. When water rights are given to those who have historically used the water in a certain area.






45. 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.






46. Ozone that exists in the trophosphere.






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






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






49. A plate boundary at which plates are moving away from each other. This causes an upwelling of magma from the mantle to cool and form new crust.






50. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.
