Population I
Name one way a
population can grow.
More births than deaths;
immigration
Population I: 200
Provide two examples of a
limiting factor
Predation, disease, natural
disaster, deforestation,
etc.
Population I: 300
Which of the following
letters would most likely
represent exponential
growth? J or S
“J”
Population I: 400
What is meant by carrying
capacity?
The maximum number of
individuals that an
environment can support
Population I: 500
Explain exponential
growth.
Exponential growth refers
to growth of a population
at a constant rate; only
under ideal conditions
Population II: 100
Name and spell the term
used to describe the
movement of individuals
into an area.
Immigration
Population II: 200
The number of organisms
per unit area is referred to
as the ___________
____________.
Population Density
Population II: 300
Can a population have a
negative growth rate? Why
or why not?
yes…a population can
have more deaths than
births
Population II: 400
List and describe two of the
three three types of
geographic distribution
1. Random- no order
2. Clumped- grouped
3. Uniform- orderly; a
pattern; evenly dispersed
Population II: 500
Is disease density-dependent
or independent? Why?
Density-dependent; disease
will only become limiting
when the population is large
and dense
Succession: 100
Would you expect
primary or secondary
succession to begin
following the event in
the above image?
Primary
Succession: 200
Secondary succession
differs from primary
succession in that ______
is still present following a
disturbance.
SOIL
Succession: 300
The end product of
ecological succession in
which a stable group of
plants and animals are
present is called the
________ _______________.
Climax Community
Succession: 400
Name an event that may
mark the beginning of the
process of secondary
succession.
Natural Disaster;
deforestation
Succession: 500
What is a pioneer species?
A pioneer species is the first species to
move into or populate an area. For
example: lichen or algae
Pioneer species are responsible for
beginning the process of soil creation.
Ecological Relationships:
100
A lion capturing and
feeding on a gazelle is an
example of this type of
ecological relationship.
Predator/Prey
Ecol. Relationships: 200
_______________ is used to
describe the relationship
between two organisms
fighting over the same
resources (e.g. food or
shelter)
Competition
Eco. Relationships: 300
This photo of a tick
attached to and surviving
off of the blood of a dog is
an example of this type of
ecological relationship.
Parasitism
Ecol. Relationships: 400
Category 4 – 40 Points
This is the type of relationship in which
both organisms benefit from one another.
Mutualism
Ecological Relationships:
500
The type of relationship in
which one organism is
benefitted while the other
organism is neither helped
nor harmed.
Commensalism
Miscellaneous: 100
Do limiting factors cause
an increase or decrease in
population size?
Decrease
Miscellaneous: 200
Does the following
population curve show
exponential or logistic
growth?
Logistic
Miscellaneous: 300
Name two events that
would expose bare rock
marking the beginning of
primary succession.
Volcanic eruption; Glacial
melting
Miscellaneous: 400
Describe what is meant by a
density-independent limiting
factor. Provide an example.
These factors are limiting to
the population regardless of
its size; weather cycles,
natural disasters, human
interference
Miscellaneous: 500
Provide an example of a symbiotic
relationship. Describe the role of each
organism in the relationship and tell
whether it is an example of mutualism,
commensalism, or parasitism.
Mutualism: Both organisms benefit
Commensalism: One benefits, one
unaffected
Parasitism: One helped, one harmed
Final Jeopardy
“The Lonliest Animals”
What was the significance of the
gate (within the pond) that
separated the male and female
rafetus turtles?
