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. Is the practice of planting bands of different crops across a hillside.






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






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






4. The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.






5. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap






6. 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






7. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.






8. The fraction of solar energy that is reflected back into space.






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






10. A waste product produced by the burning of coal.






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






12. 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.






13. An influential theory that concerns the long - term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






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






15. The act or process of transpiring - or releasing water vapor - especially through the stomata of plant tissue or the pores of the skin.






16. Organisms that consume primary consumers.






17. 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






18. Graphical representations of populations' ages.






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






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






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






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






23. Biotic and abiotic natural ecosystems.






24. 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.






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






26. Living or derived from living things.






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






28. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.






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






30. A program funded by the federal government and a trust that's funded by taxes on chemicals; identifies pollutants and cleans up hazardous waste sites.






31. Energy at rest - or stored energy.






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






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






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






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






36. The outer part of the Earth - consisting of the crust and upper mantle - approximately 100 km (62 miles) thick.






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






38. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






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






40. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






41. The second-purest form of coal.






42. Organisms in the first stages of succession.






43. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






44. 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.






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






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






47. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






48. The capacity to do work.






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






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