Questions and Answers
Which of the following best explains why the maximum sustainable yield for ocean
fisheries has been exceeded? - ANSWER-Too many fish of reproductive age are
harvested.
A sustainable society would emphasize - ANSWER-using energy efficiently and reusing
and recycling matter
Which of the following is most likely to occur in a forested region that has been recently
clear-cut? - ANSWER-The concentration of nitrates in streams running through the
region will increase.
The combustion of one gallon of automobile fuel produces about 5 pounds of carbon (in
CO2). Two autos are making a trip of 600 miles. The first auto gets 20 miles per gallon,
and the second gets 30 miles per gallon. Approximately how much less carbon (in CO2)
will be produced by the second auto on this trip? - ANSWER-50 lbs
20x5 = 100
30 x 5 = 150
150-100=50
The chart above compares the daily water use per person to the price of water in
selected countries. Which of the following conclusions can be correctly drawn using only
the data in the chart? - ANSWER-Increased water use is generally correlated with lower
water prices.
The major cause for the decline in the worldwide catch of fish since 1990 is - ANSWER-
overfishing
Sustainable use of forests in the United States would likely be encouraged by -
ANSWER-cutting small groups of medium- and large- sized trees in uneven-aged
forests
Of the following, which constitutes the greatest percent of domestic use of water in the
United States? - ANSWER-flushing toilets

gray wolf into Yellowstone National Park? - ANSWER-Enable the removal of the gray
wolf from the endangered species list
The graph above shows how seed production in a plant species varied with population
density in an unfragmented habitat (site A) and in a fragmented habitat (site B). Which
of the following conclusions is best supported by the data? - ANSWER-Habitat
fragmentation has more effect on seed production than does population density.

biodiversity? - ANSWER-Destruction of habitat and invasion by nonnative species

Having a small population size - ANSWER-1, 2, and 3
If mean global temperature keeps on increasing as predicted by contemporary
scientists, which of the following is most likely? - ANSWER-Specialist species living in
fragile ecosystems will risk extinction.
A large forested area is fragmented into small forest tracts separated by agricultural
areas. This change will most likely lead to - ANSWER-a decrease in the gene flow
within species of the original forest
Fragmenting one large park or preserve into many small parks with human habitation in
between them is most likely to lead to which of the following? - ANSWER-reduction in
species diversity
The factor that likely poses the greatest threat of extinction of species worldwide is -
ANSWER-increasing loss of habitat
High rates of species extinction caused by human activity have taken place at which of
the following times in Earth's history?
At the end of the Permian period
At the end of the Cretaceous period
