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 movement of individuals into a population.






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






3. Transition in species composition of a biological community - often following ecological disturbance of the community; the establishment of a biological community in any area virtually barren of life.






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






5. A symbiotic relationship in which both species benefit.






6. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






7. The use of building materials - building placement - and design to passively collect solar energy that can be used to keep a building warm or cool.






8. Sunlight.






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






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






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






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






13. The practice of alternating the crops grown on a piece of land - for example - corn one year - legumes for two years - and then back to corn.






14. The management of forest plantations for the purpose of harvesting timber.






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






16. The process of fusing two nuclei.






17. 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.






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






19. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






20. The process in which plants absorb ammonium (NH3) - ammonia ions (NH4+) - and nitrate ions (NO3) through their roots.






21. The bedrock - which lies below all of the other layers of soil - is referred to as the R horizon.






22. An intensification of the Greenhouse Effect due to the increased presence of heat-trapping gases in the atmosphere.






23. 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.






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






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






26. 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.






27. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






28. The result of a pathogen invading a body.






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






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






31. Any weathering that's caused by the activities of living organisms.






32. Fires that typically burn only the forest's underbrush and do little damage to mature trees. Surface fires actually serve to protect the forest from more harmful fires by removing underbrush and dead materials that would burn quickly and at high temp






33. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






34. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






35. Any compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






36. 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.






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






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






39. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.






40. The value of natural resources.






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






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






43. An animal that only consumes other animals.






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






45. A method of supplying irrigation water through tubes that literally drip water onto the soil at the base of each plant.






46. When the majority of a building's occupants experience certain symptoms that vary with the amount of time spent in the building.






47. A plate boundary where two plates are moving toward each other.






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






49. Organisms that consume primary consumers.






50. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.
