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






2. Biotic and abiotic natural ecosystems.






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






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






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






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






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






8. Any process that breaks rock down into smaller pieces without changing the chemistry of the rock; typically wind and water.






9. The carrier organism through which pathogens can attack.






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






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






12. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






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






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






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






16. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






17. When an area of vegetation is cut down and burned before being planted with crops.






18. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






19. The result of a pathogen invading a body.






20. Countries that have a renewable annual water supply of less than 1 -000 m3 per person.






21. 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.






22. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






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






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






25. The place where two plates abut each other.






26. An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.






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






28. The value of natural resources.






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






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






31. Calculating risk - or the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen.






32. Areas where cutting has occurred and a new - younger forest has arisen.






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






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






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






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






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






38. 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.






39. Resources that are often formed by very slow geologic processes - so we consider them incapable of being regenerated within the realm of human existence.






40. The finest soil - made up of particles that are less than 0.002 mm in diameter.






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






42. Graphical representations of populations' ages.






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






44. The third purest form of coal.






45. 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.






46. 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.






47. A symbiotic relationship in which both species benefit.






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






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






50. Each of the feeding levels in a food chain.
