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






2. The process by which the concentration of toxic substances increases in each successive link in the food chain.






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

6. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






7. Any other species of fish - mammals - or birds that are caught that are not the target organism.






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






9. 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






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






11. The place where two plates abut each other.






12. The movement of individuals into a population.






13. The form petroleum takes when in the ground.






14. 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.






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






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






17. Organisms that consume primary consumers.






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






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






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






21. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






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






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






24. The energy of motion.






25. States that matter can neither be created nor destroyed.






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






27. Devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.






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






29. A complex of interrelated food chains in an ecological community.






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






31. A platinum - coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust - converting them to CO2.






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






33. This category includes organisms that consume producers (plants and algae).






34. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






35. 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.






36. 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.






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






38. 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






39. 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.






40. When an area of vegetation is cut down and burned before being planted with crops.






41. The amount that the population would grow if there were unlimited resources in its environment.






42. The removal of trees for agricultural purposes or purposes of exportation.






43. When the signs and symptoms of an illness can be attributed to a specific infectious organism that resides in the building.






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






45. Power generated using water.






46. The degree to which a substance is biologically harmful.






47. 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






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






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






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