.
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.

hydroelectric power
22. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.
Aquaculture
bioaccumulation
upwelling
omnivores
23. An organism such as a bacterium or protozoan - that obtains its nourishment through the oxidation of inorganic chemical compounds - as opposed to photosynthesis.
climax community
nitrogen fixation
red tide
chemotroph (chemoautotroph)
24. Land that's fit to be cultivated.
leachate
O layer

underground mining
erosion
thermosphere
hydroelectric power
30. Poor nutrition that results from an insufficient or poorly balanced diet.
