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. 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.






2. The molten core of the Earth.






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






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






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






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






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






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






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






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






11. 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.






12. 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.






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






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






15. 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.






16. Energy at rest - or stored energy.






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






18. The effect caused by a short exposure to a high level of toxin.






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






20. Organisms in the first stages of succession.






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






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






23. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






24. Bacteria - virus - or other microorganisms that can cause disease.






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






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






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






28. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






29. Any substance than is inhaled - ingested - or absorbed at dosages sufficient to damage a living organism.






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






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






32. 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.






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






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






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






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






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






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






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






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






41. To convert or change into a vapor.






42. When one species feeds on another.






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






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






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






46. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener






47. 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.






48. A symbiotic relationship in which both species benefit.






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






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