56.1 Multiple Choice Questions
1) Philippe Bouchet and colleagues conducted a massive survey of marine molluscs on the west
coast of New Caledonia. For 20% of the total species that were located and identified, only a
single specimen was found. Which of the following claims about the diversity of molluscs in this
area is best supported by the evidence?
A) The west coast of New Caledonia is not an appropriate habitat for molluscs.
B) Many of the species from this 20% are probably rare.
C) They were not sampling uniformly throughout the area.
D) Many of the species from this 20% are most likely just dispersing through the area.
Answer: B

Learning Outcome: 56.1, Global LO: G2, V&C LO: VC-S
2) If all individuals in the last remaining population of a particular frog species were all highly
related, which type of diversity would be of greatest concern when planning to prevent the
species from going extinct?
A) global diversity
B) local diversity
C) ecosystem diversity
D) genetic diversity
Answer: D
Topic: Human activities threaten Earth's biodiversity

3) Which of the following best describes the biological significance of genetic diversity between
populations?
A) Genes for traits conferring an advantage to local conditions are unlikely.
B) The population that is most fit would survive by competitive exclusion.
C) Genetic diversity reduces the probability of extinction.
D) Diseases and parasites are not spread between separated populations.
Answer: C

, 4) Tropical forests are being converted to farm or pasture land at an alarming rate. The impact of
the deforestation on the biodiversity of the ecosystem is a major focus of research and
conservation efforts. Which of the following is a direct benefit to humans that best explains why
these forests need to be preserved?
A) Biodiversity in the tropics increases the potential to store more carbon from the atmosphere.
B) Natural and undisturbed areas are important wildlife habitats.
C) The diversity could contain novel medications for consumers.
D) The plant diversity provides unique areas for ecotourism.
Answer: C

5) Which of the following is an ecosystem service that includes processes that increase the
quality of the abiotic environment?
A) Keystone predators have a marked effect on species diversity.
B) Green plants and phytoplankton produce the oxygen we breathe.
C) Bees, flies, and wasps pollinate many plants.
D) The presence of dams improves flood control.

6) Erwin and Scott used an insecticidal spray to remove insects from the top section of an L.
seemannii tree and collect them from the forest floor. Using the data collected, Erwin projected
that this entire tree, from top to bottom, is host to about 600 unique arthropod species, which
were not found on any other tree species. While the researchers also identified 900 beetle species
from the top section, the vast majority of them were known to be found on many other tree
species. If there are approximately 50,000 species of tropical trees, and assuming that every tree
hosts a similar number of unique species, which of the following would be the best quantitative
method to roughly estimate the total number of arthropod species, globally?
A) Estimate the species density and then multiply by 50,000.
B) Multiply 600 by 50,000.
C) Multiply 50,000 by 900.
D) Add 900 to 600, and then multiply by 50,000.
