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






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






3. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






4. Each of the feeding levels in a food chain.






5. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






6. The least pure coal.






7. 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.






8. Open or forested areas built at the outer edge of a city.






9. Biotic and abiotic natural ecosystems.






10. 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.






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






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






13. A symbiotic relationship in which both species benefit.






14. When the energy released from waste incineration is used to generate electricity.






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






16. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






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






18. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






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






20. 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.






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






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






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






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






25. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






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






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






28. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






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






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






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






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






33. 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






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






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






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






37. The movement of individuals out of a population.






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






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






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






41. An estimate of the amount of fossil fuel that can be obtained from reserve.






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






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






44. 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.






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






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






47. Refers to when farmers plant seeds without using a plow to turn the soil.






48. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.






49. 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.






50. When one species feeds on another.
