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 part of the mantle that lies just below the lithosphere.






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






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






4. The number of children a couple must have in order to replace themselves in a population.






5. An effect that results from long -term exposure to low levels of toxin.






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






7. Is equal to the number of deaths per 1 -000 members of the population in a year.






8. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.






9. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






10. To convert or change into a vapor.






11. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






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






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






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






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






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






17. Radioactive wastes that produce low levels of ionizing radiation.






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






19. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






20. 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.






21. Also known as transform faults - boundaries at which plates are moving past each other - sideways.






22. The phenomenon whereby the Earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through - but absorb heat radiated back fr






23. 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.






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






25. 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.






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






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






28. Biotic and abiotic natural ecosystems.






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






30. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.






31. Ozone that exists in the trophosphere.






32. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






33. The thinning of the ozone layer over Antarctica (and to some extent - over the Arctic).






34. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.






35. A soil horizon; B receives the minerals and organic materials that are leached out of the A horizon.






36. A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and - in turn - is preyed upon by a higher member.






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






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






39. Graphical representations of populations' ages.






40. Piles of gangue - which is the waste material that results from mining.






41. The result of a pathogen invading a body.






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






43. 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.






44. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.






45. When one species feeds on another.






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






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






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






49. 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.






50. Acid rain - acid hail - acid snow; all of which occur as a result of pollution in the atmosphere.
