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






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






3. The gaseous mass or envelope surrounding a celestial body - especially the one surrounding the Earth - which is retained by the celestial body's gravitational field.






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






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






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






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






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






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






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






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






12. 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.






13. Radioactive wastes that produce high levels of ionizing radiation.






14. Living or derived from living things.






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






16. 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.






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






18. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






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






20. The least pure coal.






21. 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.






22. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






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






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






25. 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






26. An introduced - normative species.






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






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






29. The removal of all of the trees in an area.






30. A fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






31. 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






32. The movement of individuals into a population.






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






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






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






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






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






38. 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.






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






40. 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.






41. 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.






42. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.






43. The amount of time it takes for half of a radioactive sample to disappear.






44. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






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






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






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






48. Occurs when infection causes a change in the state of health.






49. 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.






50. A symbiotic relationship in which both species benefit.
