APES Chapter 6 Questions and Answers
correct
population - answer group of individuals who live in a given area at a particular time

community - answer group of interacting populations of organisms within a given
area

dynamic - answer constantly changing

population ecology - answer study of factors that influence population
increase/decrease

population size (N) - answer total number of individuals within a defined area at a
given time

population density - answer number of individuals per unit area (terrestrial) or volume
(aquatic) at a given time

management zones - answer divisions of populations by natural or human-defined
boundaries based on population density

population distribution - answer how individuals within a population are distributed
with respect to one another

random distribution - answer patternless distribution of individuals within a population
(no adaptations)

uniform distribution - answer evenly-spaced distribution of individuals within a
population (to preserve territory)

clumped distribution - answer closely-grouped distribution of individuals within a
population (to enhance feeding opportunities and predator protection)

sex ratio - answer ratio of males to females in a population; determines rate of
reproduction/size of next generation

population age structure - answer description of how many individuals fit into
particular age categories; determines those of reproductive age/size of next generation

density-dependent factors - answer factors which influence an individual's fitness
probability, in relation to population size (ex, food/water/nesting/predators)

, limiting resource - answer resource which a population cannot live without and
occurs in lower quantities than what's necessary for the population to increase in size

density-independent factors - answer factors which influence an individual's fitness
probability, unrelated to population size (i.e., environmental factors)

carrying capacity (K) - answer limit to how many individuals an environment can
sustain due to limiting resources

population growth models - answer mathematical equations used to predict
population size at any moment in time

growth rate - answer number of offspring individuals can produce (minus deaths of
individuals/offspring) in a given time period

intrinsic growth rate (r) - answer a populaton's maximum potential for growth (when
resources are not limited)

exponential growth model - answer model which estimates a population's future size
when resources are not limited (Nt = NoE^rt)

J-shaped curve - answer shape made by exponential growth model when graphed

logistic growth model - answer model which estimates a population's future size
when resources are limited (growth slows as it reaches carrying capacity)

S-shaped curve - answer shape made by logistic growth model when graphed

overshoot - answer when a population size becomes larger than the carrying
capacity (due to changes in resource availability)

die-off - answer a rapid decline in population size when carrying capacity is
exceeded and resources are limited

predator-prey control - answer predators prevent prey from overexceeding their
carrying capacity

predator-prey population oscillations - answer abundance of prey leads to
abundance in predator; prey reaches carrying capacity; decline in prey leads to delcline
in predator; abudance in prey

K-selected species - answer species with low intrinsic growth rates whose
abundance stays near carrying capacity

r-selected species - answer species with high intrinsic growth rates whose
abundance fluctuates in oscillations of overshoots and die-offs
