4. Which of the following is NOT one
of the conditions required for natural
selection?
A.
B.
C.
D.
Variability for a trait
Trait must be heritable
Trait must be dominant
Trait must lead to
differential reproduction
Differential reproduction= differences in
the survival and reproduction of different
individuals in the population due to traits.
It IS a requirement for natural selection.
While natural selection can only act upon
expressed traits (phenotype), if
homozygous recessive individuals are less
likely to survive, the recessive gene will
decrease in the gene pool.
Differential reproduction= organisms having differences in
numbers of surviving offspring due to different traits that
make the m more likely to survive/find mates.
5. Which of the following is a limit to
natural selection?
A. Favorable trait must exist
in the population.
B. Having have a high
reproduction rate.
C. Having gene mutations
D. Having differential
reproduction.
6. Natural selection which eliminates
individuals at both ends of the spectrum of
variation is called
A. Directional Selection
B. Stabilizing Selection
C. Diversifying (or
Disruptive) Selection
D. Bimodal selection
If natural selection pressure favors the average,
and acts against BOTH extremes the distribution
will narrow. Stabilizing Selection.
7. If natural selection favors one extreme
of a distribution, and acts against the other
it is called
A. Directional Selection
B. Stabilizing Selection
C. Diversifying (or
Disruptive) Selection
D. Genetic Drift
8. Interactions between two species that
results in ongoing evolutionary changes in
each species is called
A.
B.
C.
D.
Convergent evolution
Directional evolution
Diversifying evolution
Coevolution
9. Which of the following is an
example of convergent evolution.
A. Giraffes evolving longer necks
to reach high branches.
B. A newt species adapting to have
high levels of toxins because its
predator adapts by having a
tolerance to toxin.
C. Flower evolving colors to attract
bees
D. Whales and fish adapting to
water with streamlined shape
In convergent evolution, the trait is not shared by more
closely related species. The trait evolved independently in
more distantly related species because the of similarities in
natural selection pressure.
10. Which of the following would
most likely lead to speciation?
A.
B.
C.
D.
Coevolution
Stabilizing selection
Geographic isolation
Mutualistic
relationship
11. A shift in a gene pool due to
random chance …
A. is called an
adaptation
B. is called genetic drift
C. is called evolution
D. both A and C
E. is not possible
12. Genetic drift is more likely to
occur …
A. In a species with a high
reproductive rate
B. In a species with a low
reproductive rate
C. In a small population
D. In a large population
Genetic Drift
The population above shifts from being 66% brown
to 85% brown not because of an adaptive change
(a characteristic that makes the population better
suited for the environment) but because of a
random event.
Example- Polydactyly in the Pennsylvania Amish
13. When two species that compete over a food
source or habitat adapt over time to utilize the
resource in a way that avoids or reduces competition
it is called
A. Competitive exclusion
B. Interference competition
C. Resource partitioning
D. Resilience
14. Which of the following would most
likely cause adaptive radiation to occur?
A. The introduction of
an invasive species
B. A mass extinction
C. Human population
growth
D. Long term stability
in the climate
Adaptive radiation (many
species evolve from an
original ancestor) may occur
when there are many
available niches.
Mass extinctions may create
available niches.
The differing conditions
of the Galapagos Islands
created different
available niches.
15. Specialist species have a _____ niche and
have an advantage in a ______ environment.
A.
B.
C.
D.
broad; stable
narrow; stable
broad; rapidly changing
narrow; rapidly changing
16. Endemic species are
A. species that are found
nowhere else
B. species that serve as early
warnings that a community
is being damaged
C. species that play a critical
role in the ecosystem
D. species that spread disease
17. Exploitation competition occurs
when
A. One species limits another
species’ access
B. One species uses the
resource more efficiently
18. Typical trends in succession is for diversity
to ______ with time and for plant size to ______
with time.
A.
B.
C.
D.
both increase
both decrease
increase; decrease
decrease; increase
19. The trees in a mature/climax community in a
temperate deciduous forest biome generally _______
than trees earlier in the succession process.
A. are slower growing
B. have higher light
requirements
C. have lower light
requirements
D. A and B
E. A and C
In ecological succession, faster
growing plants are replaced
over time by slower growing
species that are better able to
compete for light and other
resources.
20. Inertia (or persistence) is ability of an
ecosystem.
A. recover after a
disturbance.
B. survive minor ecological
disturbances.
C. develop into a
mature/climax
community.
D. to expand its range.
21. Rainforest have a high level of biodiversity but very
poor soil (because with very high productivity nutrients
get used up quickly and are store in the high biomass of
the rainforest. These conditions causer rainforest to have
_____ inertia/persistence and _____ resilience.
A.
B.
C.
D.
high; low
low; high
both high
both low
The high biodiversity creates many available niches- so that a
rainforest has more inertia to withstand minor ecological
disruptions.
However, with very poor soil, a rainforest is not resilient and
generally can not rebound well from major ecological
disruptions.
22. The top two causes of loss of biodiversity
are
A. habitat loss and
pollution
B. habitat loss and
invasive species
C. pollution and
invasive species
D. invading hippos and
elephants

characteristic that might make a species
extinction-prone?
A.
B.
C.
D.
low on the food chain
low reproductive rate
specialist
Commercially valuable
Organisms that are HIGHER on the food chain must
be supported by a greater biomass of the previous
levels.
24. Which of the following is NOT a
reason that migratory birds are so hard
to protect?
A. They cross country
boundaries.
B. They often nest in
wetlands.
C. They are often
generalists.
D. They require a lot of
habitat.
25. The Endangered Species Act
A. requires a plan to
protect endangered
species while taking into
consideration economic
impact.
B. is directed by the EPA.
C. protects only species
living on federal lands.
D. All of the above
26. An international ban on trade of
ivory is part of
A. ESA
B. Convention on
Biological Diversity
C. CITES
D. Montreal Protocol
E. Kyoto Protocol
CITES =
Convention on International Trade of Exotic Species
27. A smaller island (or wildlife
preserve) is expected to have a lower
species diversity because
A.
B.
C.
D.
E.
F.
a higher rate of extinction
a lower rate of extinction
a higher rate of immigration
a lower rate of immigration
Both A and D
Both B and C
Theory of
Island Biogeography
The point at which the
immigration line intersects the
extinction line predicts the
number of species.
Small islands generally have a lower migration rate because they are a
smaller target for migrating species.
Small islands generally have a higher extinction rate because they have
fewer available resources/ niches.
