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!!
