Both organisms
benefit from
living together.
Mutualism
An association where
one organisms benefits,
while the other neither
benefits nor is harmed.
Commensalism
A long term
relationship in which
one organism obtains
nutrients from
another.
Parasitism
A close relationship
between two organisms
of different species. Ex.
microbes located in the
digestive tract.
Symbiosis
The use or defense of a
resource by one
individual that reduces
the availability of that
resource to other
individuals.
Competition
The process by which
inorganic materials
move from the
atmosphere to soil, into
living organisms and
back again.
Biogeochemical
Cycles
T/F During
ammonification,
bacteria convert
nitrogen gas into
ammonium compounds.
False
An increase in the
ability of the
atmosphere to trap
heat.
Greenhouse
Effect
The cycle that
photosynthesis and
respiration are the
base for.
Carbon-Oxygen
Cycle
Convert nitrogen gas
(N2) into ammonium
compounds
(NH4OH).
Nitrogen
Fixation
The way of life
of a species.
niche
The nonliving
parts of the
environment.
abiotic factors
An ecological unit that
includes all the
interacting parts of an
environment in an
area. Ex. a cave, a
pond
ecosystem
All the living
organisms that inhabit
an environment. Ex.
plants, animals,
protists
biotic factors
The portion of Earth
that sustains life. It
extends from high in
the atmosphere to the
bottom of the oceans.
biosphere
These are
autotrophic
organisms that
manufacture their
own food
producers
This means that
it must consume
food to get
energy.
Heterotroph
These
heterotrophs can
be classified into
two main groups.
Primary and
Secondary
Consumers
This group of
organisms break
down dead tissue
and animal wastes.
Decomposers
What are the 4
classifications of
consumers based
on what they eat.
Herbivores,
Carnivores,
Omnivores,
Scavengers
Interrelated
food chains in an
ecosystem is
call?
Food
Web
A specific sequence
in which organisms
get energy in an
ecosystem.

Biomass Pyramid
What are the 4
steps to the
water cycle?
Condensation
Precipitation
Transpiration
Evaporation
A state of severely
reduced physiological
activity during the
winter months.
Hibernation
Competition
between
organisms of the
same species
Intraspecific
Competition
What are the 3 steps
of the Nitrogen
cycle?
Nitrogen Fixation
Ammonification
Denitrification
A cycle of activity
occurring every 24
hours. (ex. Pedals of a
flower opening in the
morning and closing in
the evening.
Circadian Rhythm
