ANSWERS) /ALREADY GRADED A+



A population is correctly defined as having which of the following
characteristics?
A. live and reproduce in the same general area
B. belonging to the same species
C. possessing a constant and uniform density and dispersion - ANSWER
A&B


An ecologist recorded 12 white-tailed deer, Odocoileus virginianus, per square
mile in one woodlot and 20 per square mile in another woodlot. What was the
ecologist comparing?
A. density
B. dispersion
C. carrying capacity
D. cohorts
E. range - ANSWER A


Which of the following choices would most likely promote random
distribution?
A. territorial species
B. species that secrete chemicals to attract or inhibit other individuals
C. flocking and schooling behaviors
D. spacing during the breeding season
E. homogeneous chemical and physical factors in the environment - ANSWER
E

,Consider two forests: one is an undisturbed old-growth forest, while the other
has recently been logged. In which forest are species likely to experience
exponential growth, and why?
A. Old growth, because of stable conditions that would favor exponential
growth of all species in the forest.
B. Old growth, because each of the species is well established and can
produce many offspring.
C. Logged, because the disturbed forest affords more resources for increased
specific populations to grow.
D. Logged, because the various populations are stimulated to a higher
reproductive potential.
E. Exponential growth is equally probable in old-growth and logged forests. -
ANSWER C


Which of the following causes populations to shift most quickly from an
exponential to a logistic population growth?
A. increased birth rate
B. removal of predators
C. decreased death rate
D. competition for resources
E. favorable climatic conditions - ANSWER D


Which of the following is characteristic of K-strategists?
A. Have offspring with good chances of survival
B. Have many offspring per reproductive episode
C. Have small offspring
D. Have a high intrinsic growth rate
E. Early parental reproduction - ANSWER A


Which of the following is most likely to contribute to density-dependent
regulation of populations?
A. the removal of toxic waste by decomposers
B. intra-specific competition for nutrients
C. floods

,D. fires - ANSWER B


Why do populations grow more slowly as they approach their carrying
capacity?
A. Density-dependent factors lead to fewer births and increased mortality.
B. Density-independent factors lead to fewer births and increased mortality.
C. Hormonal changes promote higher death rates in crowded populations.
D. Individuals voluntarily stop mating so that overcrowding does not occur.
E. The incoming energy decreases in populations experiencing a high rate of
increase - ANSWER A


As N approaches K for a certain population, which of the following is predicted
by the logistic equation? Select one:
A. The growth rate will not change.
B. The growth rate will approach zero.
C. The growth rate will increase
D. The population will increase exponentially.
E. The carrying capacity of the environment will increase - ANSWER B


A population of ground squirrels has an annual per capita birth rate of 0.06
and an annual per capita death rate of 0.02. Calculate an estimate of the
number of individuals added to a population of 1,000 individuals in one year
(so that is the growth of the population.
Select one:
A. 120
B. 40
C. 20
D. 400 - ANSWER B


Which of the following statements is consistent with the principle of
competitive exclusion?
Select one:
A. Bird species generally do not compete for nesting sites.

, B. The random distribution of one competing species will have a positive
impact on the population growth of the other competing species.
C. Two species with the same fundamental niche will exclude other competing
species.
D. Even a slight reproductive advantage will eventually lead to the elimination
of the less well adapted of two competing species.
E. Natural selection tends to increase competition between related species -
ANSWER D


Which of the following are density dependent limits on the population growth
of a field mouse species?
Select one or more:
A. drought (not enough rain)
B. Kitty cats
C. communicable diseases
D. forest fire - ANSWER C


Glacier Bay in Alaska is a fjord whose lowlands were covered by glacial ice
until around 230 years ago. As the glacier retreated, glacial till was exposed to
plant colonization; remarkably (and fortunately for generations of ecologists),
the location of the tip of the retreating glacier has been frequently documented
since the late 1700's. One of the first species to colonize a newly exposed area
of glacial till is fireweed. Many of its seeds will fall on rock and be unable to
germinate, but some will find purchase, few of these will reach reproductive
maturity. Which terms most appropriately characterizes fireweed? Select one:
A. K-strategist
B. r-strategist
C. keystone species
D. dominant species - ANSWER B


An ecologist recorded 12 white-tailed deer, Odocoileus virginianus, per square
mile in one woodlot and 20 per square mile in another woodlot. What was the
ecologist comparing? Select one:
A. density
