POPULATIONS &
COMMUNITIES
REVIEW
The nonliving things within
the environment.
ABIOTIC FACTORS
The living things within the
environment.
BIOTIC FACTORS
Level of organization below
community; a group of
these form a community.
POPULATIONS
Can you name one of the
characteristics/factors
used to study a
population?
• DENSITY
• SIZE
• SPACE
Can you name one of the
characteristics/factors that
determine an organism’s
niche?
• DIET
• INTERACTION WITH OTHER
ORGANISMS
• MEANS OF GETTING FOOD
During predation, what do
you call the organism that
does the hunting?
PREDATOR
What do you call two
species of organisms that
live in the same community
and compete over
resources?
COMPETITORS
Can you give one example
of an abiotic factor?
• WATER
• SUNLIGHT
• OXYGEN (AIR)
• TEMPERATURE
(WEATHER/CLIMATE)
• SOIL (LAND/TOPOGRAPHY)
The study of interactions
that take place between
organisms within their
environment.
ECOLOGY
A single individual from a
population.
ORGANISM
The biotic communities
and the abiotic factors that
affect them..
ECOSYSTEM
The contest among
organisms to obtain the
resources they need to
survive and reproduce.
COMPETITION
A symbiotic relationship
that benefits both species.
MUTUALISM
The physical location
where an organism lives.
HABITAT
Name for a species that is
first to inhabit a new area
primarily after a volcanic
eruption.
PIONEER
Type of ecological
succession that begins in a
place that does not have
soil and has never
supported living
organisms.
PRIMARY
In addition to sunlight and
precipitation, what other
abiotic factor affects plant
growth?
TEMPERATURE
(WEATHER/CLIMATE)
Type of ecological
succession that occurs in
an area that has soil and
was once the home of
living organisms.
SECONDARY
Any abiotic factor that
restricts the number of
individuals in a population.
LIMITING FACTOR
The size of a population
occupying an area of
specific size.
POPULATION DENSITY
The largest number of
individuals an environment
can support and maintain
for a long period of time.
CARRYING CAPACITY
The part of the Earth that
supports living organisms;
largest level of
organization for life.
BIOSPHERE
The feeding of one
organism on another.
PREDATION
The role of an organism in
an ecosystem.
NICHE
Type of relationship where
one organism benefits and
the other harms its host.
PARASITISM
Any close relationship
between two or more
different species.
SYMBIOSIS
A type of relationship
where one partner benefits
and the other is neither
helped nor harmed.
COMMENSALISM
Do you know the difference
between abiotic and biotic
factors? Can you give
examples of each?
Do you know the difference
between mutualism,
parasitism, and predation?
Can you give an example of
each?
Can you compare/contrast
primary and secondary
succession?
It’s a new year . . . Resolve
to study more and give
nothing but your best!
GOOD LUCK!!
