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






2. Organisms in the first stages of succession.






3. A group of organisms of the same species that live in the same area.






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






5. 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.






6. When one species feeds on another.






7. 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.






8. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






9. Biotic and abiotic natural ecosystems.






10. Organisms that consume primary consumers.






11. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






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






13. To convert or change into a vapor.






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






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






16. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






17. Using strategies to reduce the amount of risk (the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen).






18. Non-moving sources of pollution - such as factories.






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






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






21. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






22. Organisms that consume both producers and primary consumers.






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






24. The capacity to do work.






25. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






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






27. 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.






28. Pollutants that are released directly into the lower atmosphere.






29. The movement of individuals into a population.






30. The process that occurs when two different species in a region compete and the better adapted species wins.






31. The molten core of the Earth.






32. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






33. The point at which 50 percent of the test organisms die from a toxin.






34. Being extinct or the process of becoming extinct.






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






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






37. The dosage level of a toxin at which a negative effect occurs.






38. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.






39. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






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






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






42. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






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






44. The third purest form of coal.






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






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






47. 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.






48. The amount of energy that plants pass on to the community of herbivores in an ecosystem.






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