Instructions:
Answer 50 questions in 15 minutes.

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

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

photochemical smog
atmosphere
crude oil
20. A group of modern windmills.
sick building syndrome

water-scarce
22. 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.

mutualism
26. The water from which a river rises; a source.
producer

27. 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.
solid waste
Gross Primary Productivity
k-selected
fission
28. The result of chemical interaction with the bedrock that is typical of the action of both water and atmospheric gases.
autotroph
net Primary Productivity (NPP)
chemical weathering
vector
29. When one species feeds on another.
Hadley cell
clay
transform boundary
predation
30. Says that energy can neither be created nor destroyed; it can only be transferred and transformed.

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