All of the biotic and abiotic
factors that describe where an
organism lives.
What is habitat?
Definition of niche.
What is all the physical,
chemical, and biological factors
that an organism needs to stay
healthy and reproduce?
Define competitive exclusion.
What is when 2 species are
competing for the same
resources, one that is better
suited out competes the other,
which goes extinct or is forced
out?
The term that describes
when competitive
exclusion results in a
division of the resources
between the 2 species.
What niche partitioning?
Define ecological equivalents.
What are species that occupy similar
niches, but live in different
geographic areas?
The definition of competition.
What is when 2
organisms fight for
limited resources?
A +/- interaction where an
organism gets consumed.
What is predation?
The +/+ relationship you learned
about.
What is a mutualism?
The definition of commensalism.
What is a close relationship where
one organism benefits and the
other is not harmed (0)?
The term describing an
organism that lives in or
on another organism while
receiving its nutrition from
that organism.
What is parasitism?
A population that lives in a
cluster.
What is clumped?
Nesting sea birds have a _____
dispersal pattern and solitary
owls have a _______ dispersal
pattern.
What is uniform and random?
This is how you calculate
population density.
What is divide the number of
individuals by the area?
Type II survivorship curves look like
this because ….
What linear and they have about
the same number of individuals
die throughout their life span?
This is what a Type III
survivorship curve looks like and
this is an example of an organism
with this type of curve.
What is it drops very fast initially
and then slows down later on
(opposite of exponential growth)?
What is salmon, invertebrate etc.?
Growth that is unchecked by
limits is called….
What is exponential?
When you add in limits to
population growth, you get this
kind of growth.
What is logistic growth?
Explain the dotted line on the
logistic growth graph and apply the
correct term for it.
What is carrying capacity and
the maximum number of individuals
of a certain species that an
environment can support?
A limiting factor whose strength
changes depending on how many
organisms of a certain species are
present, give an example.
What are density dependent limiting
factors and parasitism or disease?
Define density independent
limiting factors and give an
example.
What are aspects of the environment
that limit a population’s growth
regardless of the density of the
population? What is an ice storm,
hurricane, volcano etc.?
The sequence of biotic
changes that regenerate
an area after a
disturbance.
What is succession?
Recovery from a disturbance
where no soil is left & that also
takes a long time.
What is primary succession?
The definition of secondary
succession.
What is recovery from a
disturbance where soil is left &
organisms can colonize from
nearby undisturbed areas ?
The definition of a pioneer species
and an example.
What is the first organisms to
recolonize and occupy an area
after a disturbance? What are
dandelions or some other weed?
The nutrient cycles from
chapter 13 are related to
succession in this way.
You need to talk about at
least 2 cycles.
What is weathering needs to happen for
Phosphorus to be present/ the rocks need to
break down?
What is bacteria need to recolonize for
there to be Nitrogen for the plants to use,
so eventually animals can reestablish?
