The number of
individuals per
unit area.
What is
population density?
These 3 factors affect
population size.
What are # of
births, # of deaths,
and #entering or
leaving?
Under ideal
conditions,
populations grow this
way.
What is
exponential
growth?
When resources
become less
available, this type of
growth occurs.
What is
logistic
growth?
The largest # of
organism that the
environment can
support.
What is the
carrying
capacity?
These cause
population growth to
decrease.
What are limiting
factors?
These factors affect
populations only
when they reach a
certain density.
What are densitydependent limiting
factors?
Examples include
weather, human
activity, and natural
disasters.
What are densityindependent limiting
factors?
Examples include
competition,
predation, and
disease.
What are densitydependent limiting
factors?
Parasites are this type
of limiting factor.
What is densitydependent?
This kind of growth
is represented by a Jshaped curve
What is
Exponential growth?
2 factors that caused
human growth rate to
become exponential.
What are improved:
agriculture, industry,
transportation,
sanitation, medicine,
and health care ?
Individuals move
into a population
What is immigration
Individuals move out
of a population
What is emigration
Splitting an
ecosystem into
smaller pieces
What is habitat
fragmentation
The variety of
organisms in the
biosphere.
What is
biodiversity?
Species of many
kinds have provided
these 3 things for us.
What are food,
medicine, and
industrial products?
Humans reduce
biodiversity in these
3 ways.
What are: altering
habitats; overhunting;
introducing toxic
compounds into food;
and introducing invasive
species?
Toxic compounds
increase in organisms
at higher trophic
levels. This is:
What is biological
magnification?
3 examples of
invasive species
What are: zebra
mussels, gypsy moth,
Asian carp, honeysuckle, starlings,
kudzu, etc.?
When a species no
longer exists.
What is
extinct?
When a species is
declining in
numbers, and may
become endangered.
What is
threatened?
When a species in
danger of extinction
What is endangered
What is the biggest
threat to biodiversity?
What is human
activity?
The factor that is
measured during an
experiment (what you
find out).
What is the DV?
