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






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






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






4. The unit used to describe the volume of fossil fuels.






5. 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.






6. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.






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






8. Ozone that exists in the trophosphere.






9. Organisms that consume both producers and primary consumers.






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






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






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






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






14. Being extinct or the process of becoming extinct.






15. The process of fusing two nuclei.






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






17. A layer of soil.






18. The result of a pathogen invading a body.






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






20. 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.






21. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.






22. The movement of individuals into a population.






23. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






24. The day-to-day use of environmental resources as food - clothing - and housing.






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






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






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






28. The region draining into river system or other body of water.






29. The raising of fish and other aquatic species in captivity for harvest.






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






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






32. A symbiotic relationship in which both species benefit.






33. Species that originate and live - or occur naturally - in an area or environment.






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






35. Pollutants that are formed by the combination of primary pollutants in the atmosphere.






36. The least pure coal.






37. Any noise that causes stress or has the potential to damage human health.






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






39. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






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






41. An estimate of the amount of fossil fuel that can be obtained from reserve.






42. 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






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






44. 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.






45. 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.






46. A system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.






47. The part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life.






48. 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.






49. Pollution that does not have a specific point of release - open -loop recycling -when materials are reused to form new products.






50. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.
