Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can

.
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.

ecosystem capital
non-point source pollution
16. The fraction of solar energy that is reflected back into space.
shelter-wood cutting
albedo
wastewater
extinction
17. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels - especially coal.
prior appropriation
preservation
driftnets
gray smog (industrial smog)
18. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.
peak oil (Hubbert peak)
birth rate (crude birth rate)
arable
shelter-wood cutting
19. 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.
fly ash
erosion
drip irrigation

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

21. When one species feeds on another.

no-till
wastewater
22. Organisms that derive energy from consuming nonliving organic matter.
biotic
detritivore
humus
ecological footprint
23. 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
surface fires
Aquaculture

25. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.
demographic transition model
surface fires
long lining

26. 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).
jet stream
crude oil
upwelling
fishery
27. The energy of motion.
