4.1 Define Ecology
4.1 Define Species.
4.1 Define population
Define population ecology
4.1 Define community
Define community ecology
4.1 What does an
ecosystem include?
4.1 What is the difference
between a species and a
population?
4.1 What is the difference
4.1 What does ecosystem
between a population and a ecology study?
community?
4.1 What is the biosphere? 4.1 Describe the difference
between biotic and abiotic
What do scientists that
factors.
study ecology at the
biosphere level examine?
4.1 Define habitat.
Define ecosystem.
What is the difference
between them.
4.1 Define what a resource
is.
How do resources affect
population growth?
4.2 What are the three
main terms scientists use
to describe populations?
4.2 What increase a
population’s size?
4.2 What decreases a
population’s size?
4.2 Why do scientists use
sampling to estimate the
size of a population?
4.2 Describe how to
perform random sampling.
4.2 Describe the mark and
recapture method of
population sampling.
4.2 Define population
density.
4.2 What are the three
types of population
distributions?
4.2 How are population
distributions in nature
typically arranged?
4.2 Describe clumped
distribution.
4.2 Describe Random
distribution.
4.2 Describe uniform
distribution.
4.2 What is the difference
between density and
distribution?
4.2 What are age structure
diagrams?
4.2 What are age structure
diagrams used to predict?
4.2 How can high
population density be
helpful to a population?
4.2 How can high
population density be
harmful to a population?
4.2 What will happen to a
population made up mostly
of individuals that are past
reproductive
age?
4.2 What can you predict
about a population with an
age-structure diagram
shaped like a
pyramid?
4.2 Describe how you might use
population distribution to find
the sources of food or other
resources used by a species.
4.2 Explain the significance of
an age-structure diagram in
which the bars are short along
one side and long on the
opposite side.
4.2 How is a population’s
size related to its’ well
being?
4.3 What determines a
population’s growth rate?
4.3 What is the growth rate
equation?
Be able to use it.
4.3 What is natality?
4.3 What is mortality?
4.3 What does survivorship 4.3 Describe organisms
curves show?
mortality that have a type 1
survivorship curve.
4.3Describe organisms
4.3Describe organisms
mortality that have a type 2 mortality that have a type 3
survivorship curve.
survivorship curve.
4.3 Which type of
survivorship curve
describes populations
whose mortality is highest
at young ages?
4.3 What is immigration?
How does it affect the
populations size?
4.3What is emmigration?
How does it affect the
populations size?
4.3 Define migration.
How does it affect a
populations size?
4.3 Describe exponential
growth.
4.3 Describe logistical
growth.
4.3 What is carrying
capacity? Where is it on a
graph?
4.3 How do limiting factors
affect the populations size?
4.3 Which type of growth is
shown most often in
nature?
Why?
4.3 What are density
dependent factors? Give an
example.
What are density independent
factors? Give an example.
4.3 What is biotic potential? 4.3 What is gestation time?
How does it affect a
What is generation time?
population?
How do these factors affect
a population?
Lab: Describe how to
Lab: Describe how to
perform Random Sampling perform mark and
recapture.
Case Study: Why was the
disappearance of the
Golden Toad odd?
Case Study: Why did the
Golden Toad’s population
become decimated so
quickly and eventually
become extinct?
