Environmental Science

During the agricultural revolution

• fossil fuel use increased

• plants and animals were domesticated

• human populations decreased due to disease

• Both (a) and (b)

Which of the following is a developing nation?

• France

• Canada

• Ethiopia

• United States

Which best describes the use of a renewable resource?

• filling a car with gasoline

• mining copper

• building wooden furniture

• burning coal in a power plant

Using economic considerations of resource use, the law of supply and demand describes

• the availability of abundant resources

• the worth of nonrenewable resources

• reduced demand resulting from a lack of available resources

• the relationship between the availability and the worth of resources

Organisms can adapt to

• their physical surroundings

• other organisms

• Both (a) and (b)

• Neither (a) nor (b)

Which of the following best describes a population

• all types of organisms living in the same place

• all members of the same species

• members of the same species living in the same place at the same time

• all the red birds in an area

Single-celled organisms with cell walls but no nuclei are

• bacteria

• fungi

• protists

• All of the above

Which gas makes up 78% of our atmosphere but can be used by plants only when transformed by bacteria first

• hydrogen

• carbon dioxide

• oxygen

• nitrogen

Where would an ecologist be least likely to go to study primary succession

• a new island formed by a volcanic eruption

• the Amazon Rain Forest

• a gravel-filled valley that had been covered by a glacier until recently

• a locked, abandoned asphalt parking lot in New York City

Plants play a crucial role in the carbon cycle because they

• are chemically converted into fossil fuels when burned

• do not release carbon dioxide during cellular respiration

• allow carbon to enter an ecosystem through photosynthesis

• have special bacteria that live in their root systems
