D) an oxygen atom is transferred from nitrogen dioxide to an oxygen molecule
4.
How do greenhouse gases support life on Earth?

B) They absorb infrared radiation, which keeps Earth's surface warm.
C) They form carbon dioxide, which is absorbed by fossil fuels.
D) They pass the energy from sunlight to chlorophyll for use in photosynthesis.
5.
What is global warming?
A) the normal temperature fluctuations of Earth's climate cycle
B) the melting of the polar ice caps
C) the trend of increasing temperatures on Earth

6.
What may happen when a lake ecosystem becomes polluted with fertilizers?
A) increase in dissolved oxygen
B) eutrophication
C) increased rate of decomposition by detrivores

7.
Why are frogs considered an indicator species for water quality?
A) They are easily killed by direct contact with pollutants.
B) They are able to break down pollutants.
C) They come into direct contact with pollutants and show readily observed effects like deformities.
D) They develop diseases when they come in direct contact with pollutants.

9.
How do fat-soluble pollutants move from one species to another through biomagnification?
A) They dissolve in water in organisms and are eliminated into lakes as waste.
B) They move up the trophic structure from carnivores to herbivores.
C) They accumulate only in the cytoplasm of herbivores' cells.
D) They are stored in body tissues that are eaten by predators.
10.
What kind of organism is most seriously affected by biomagnification?
