BIO 322 self quiz questions 2 ch 6, 12, 13, 14 With Complete
Solutions
According to the figure below, studies comparing organic and
conventional farms tend to find that organic farms
A. growing fruits have yields that are on average about equal to
those from conventional producers.
B. growing either cereals or vegetables have greater yields than
conventional producers.
C. harbor a greater diversity of organisms than found on
conventional farms.
D. have lower yields than conventional producers, regardless of
the type of crop. Correct Answers A
The ratio of yields for organic versus conventional fruit
producers was about 1, indicating no difference.
Agricultural practices associated with the Green Revolution
A. dramatically boosted crop yields and made possible the rapid
growth of the human population.
B. negatively affected aquatic environments due to the use of
massive quantities of synthetic fertilizers.
C. harmed wildlife due to the widespread use of pesticides, such
as DDT.
D. are accurately described by all of the above statements.
Correct Answers D
Green Revolution agricultural practices greatly increased yields,
but the use of large amounts of pesticides and synthetic
fertilizers has had negative consequences for both aquatic and
terrestrial environments.
,An ecoregion is a large area of land or water that
A. corresponds to geopolitical boundaries.
B. is delineated by features such as mountains, canyons, or
rivers.
C. is characterized by a relatively distinct set of environmental
conditions and species.
D. None of the above Correct Answers C
An ecoregion does not necessarily follow geopolitical
boundaries and is instead defined by the relatively unique
environmental conditions and species found within the region.
Assuming the objective is to maximize the chance of success
while minimizing the economic costs, using the figure below,
which woodland caribou herd might get top priority for
protection and restoration?
A. A La Peche (ALP)
B. East Athabasca River (ESAR)
C. West Athabasca River (WSAR)
D. Slave Lake (SL) Correct Answers A
This herd has a relatively high chance of persistence combined
with low costs for protection and restoration.
Compared to a more plant-focused diet, a diet rich with meat has
A. a smaller carbon footprint and smaller water footprint.
B. a larger carbon footprint but a smaller water footprint.
C. a smaller carbon footprint but a larger water footprint.
, D. a larger carbon footprint and a larger water footprint. Correct
Answers D
Production of meat generally requires more energy and more
water than an equivalent number of plant calories.
Conservation International (CI) identified 25 biodiversity
hotspots as areas harboring especially large numbers of
A. threatened and endangered plant and animal species.
B. endemic animal species combined with low rates of habitat
conversion.
C. plant and animal species.
D. endemic plant species combined with high rates of habitat
conversion. Correct Answers D
CI's hotspots harbor at least 2,500 endemic plant species and
have lost at least 70% of their original vegetation due to land
conversion.
Conservation planners can incorporate the anticipated effects of
climate change by identifying areas that
A. encompass both the current and the projected future
distribution of conservation targets.
B. capture the entire spectrum of soil types, topographic
features, and climatic conditions.
C. provide for the continuation of key ecosystem processes such
as sediment retention along a river.
D. may achieve any of the above. Correct Answers D
Conservation planners are adapting their plans to account for the
anticipated effects of climate change in all three of the above
ways.
