5. Chapter 56 points out that many endangered or extinct species live in freshwater habitats, such as along the Mississippi River. Chapter 55 mentions that eutrophication has been one major source of freshwater destruction and damage. Since nitrogen is a major contributor to eutrophication, one good solution would be to
breed varieties of duckweed that absorb lots of phosphorus.
fertilize cornfields during the summer instead of in spring.
grow crops that need less nitrogen fertilizer.
require all wastewater dumped in the Mississippi River to go through a wastewater treatment facility first.
build more levees so the river runs to the Gulf of Mexico faster.

6. an increase in feral dogs. a lack of genetically diverse males.
Figure shows the Illinois prairie chicken population between 1970 and This figure shows that egg viability declined sharply as the number of males decreased. However, the text says that there used to be millions of prairie chickens in Illinois in the 19th century. The graph doesn’t go back that far, but the most important reason for the large reduction in prairie chickens between 1850 and 1950 was
a skewed sex ratio.
habitat loss.

the population fell below its MVP.

8. Figure shows the amount of land needed to protect the grizzly bear population in western Wyoming. Assume there are no changes to park size in the future. From this figure, you can predict that
where there are grizzly bears, there will be wolves.
grizzly bears will probably disappear from Wyoming.
grizzly bears will learn not to bother people.
there are 50 grizzly bears living in Yellowstone National Park.
more bears live outside the parks than inside the parks.

9. Costa Rica has established an extensive network of national parks and buffer zones to protect its biodiversity. However, a recent study showed that habitat loss outside these zones is large. This shows that
Costa Rica is too small.
habitat zones don’t work.
biodiversity can take care of itself.
protecting biodiversity is difficult.
the laws need to be enforced better.

10. Biophilia means our connection to nature and love of other forms of life. Biophilia is
a new religious concept, closely associated with new age religions.

a way to describe the common belief that other species are entitled to life.
a theory to explain people who hang animal heads on their walls.
a new form of deviant sexuality.

11. A good time to protect a species is when
it joins the 100 heartbeat club.
it reaches its MVP.
it becomes extinct.
we notice it is declining but not endangered.
