4 A quadrant study is:

B a study of a large area such as an entire ecosystem

C a study tracking changes in a small section of the environment

D a study that follows an organism's reproductive patterns

5 The greenhouse effect involves:

A energy from the sun being trapped within the atmosphere & warming an area

B energy from the sun being trapped within the atmosphere & cooling the area

C energy from the sun causing carbon dioxide to turn into a solid

D energy from the sun converting halides into noble gases

6 The __________ is connected to a rise in atmospheric CO2 & corresponding temperatures.

B Industrial Revolution

C Manhattan Project

D Technology Boom

7 The number of organisms of one species that live in a specific area defines:

A a community

B an ecosystem

C a population

D a biome

8 Lakes undergo turn over throughout the changing seasons because:

B The epilimnion takes up all of a deep lake such as one of the Great Lakes

C The hypolimnion is at a higher density than the epilimnion

D The lakes are not affected by tides or currents so the daily temperature associated with depth stays constant
