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 order2.Clumped- grouped3.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 algaePioneer 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: 300This 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: 400Category 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 benefitCommensalism: One benefits, one
unaffectedParasitism: 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?
