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 the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






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






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






4. This category includes organisms that consume producers (plants and algae).






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






6. 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.






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






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






9. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels.






10. Drilling a hole in the ground that's below the water table to hold waste.






11. A layer of soil.






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






13. Change in the genetic composition of a population during successive generations as a result of natural selection acting on the genetic variation among individuals and resulting in the development of new species.






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






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






16. The point at which 50 percent of the test organisms die from a toxin.






17. The area or environment where an organism or ecological community normally lives or occurs.






18. A semiconductor device that converts the energy of sunlight into electric energy.






19. The form petroleum takes when in the ground.






20. A group of modern windmills.






21. 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.






22. 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.






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






24. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






25. An animal that only consumes other animals.






26. The water from which a river rises; a source.






27. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






28. The result of chemical interaction with the bedrock that is typical of the action of both water and atmospheric gases.






29. When one species feeds on another.






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






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






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






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






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






35. Sunlight.






36. 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






37. Soil composed of a mixture of sand - clay - silt - and organic matter.






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






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






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






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. Radioactive wastes that produce high levels of ionizing radiation.






43. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






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






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






46. The third purest form of coal.






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






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






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






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