I can name the 3 types of relationships in
ecology
I can list the 2 types of nutritional
relationships
I can define “auto”
I can define “troph”
I can define an autotroph
I can give an example of an autotroph
I can define “hetero”
I can define a heterotroph
I can give an example of a heterotroph
I can list the 4 types of heterotrophs
I can define an herbivore
I can give an example of an herbivore
I can define a carnivore
I can give an example of a carnivore
I can define an omnivore
I can define an example of an omnivore

relationships

I can explain parasitism
I can give an example of parasitism
I can explain commensalism
I can give an example of commensalism
I can list 2 other animal interactions
I can explain competition
I can explain predation

Interactions

Autotroph


Auto- means “self”
-troph means “feeder”
So, an autotroph is an organism that makes its
own food
Heterotroph
Grasses & flowers are
autotrophs
A horse is a
heterotroph



Hetero- means “other”
-troph means “feeder”
So, a heterotroph is an organism that cannot
make its own food

A heterotroph that
eats only plants

A heterotroph that
eats only animals

A heterotroph that
eats both plants
and animals

A carnivore that eats
only already-dead
animals
Symbiosis – a close relationship between two organisms of different species that
benefits at least one of the organisms

•Mutualism
•Parasitism
•Commensalism
A close relationship
between organisms
of two species in
which both
organisms benefit
The sea anemone and
the clown fish have a
mutualistic
relationship. This
means they both
benefit. The clown fish
benefits because it
gets a habitat that is
very safe from other
predators. The sea
anemone (the plant)
benefits because the
clown fish’s movement
allows more seawater
in, which allows it to
eat more.
A close relationship
between organisms
of two species in
which one organism
lives on or in a host
and harms it
The dog and tick
have a parasitic
relationship. The tick is
the parasite, which is
the organism that
benefits. It gets a free
meals and place to
live. The dog is the
host, which is the
organism where a
parasite lives. The dog
is harmed and can
get very sick.
A close relationship
between organisms
of two species in
which one species
benefits and the
other is not helped
or harmed
The whale and the
barnacles show
commensalism. The
barnacles benefit
because they get
much more sea water
access, which gives
them more food. They
also get a free place
to live. The whale is not
helped or hurt by the
barnacles.
Competition

The struggle between
organisms to survive as
they attempt to use
the same limited
resource
Predation

An interaction in which
one organism kills another
for food
The organism that does the killing in a
predation interaction

The organism that is killed and eaten by
another organism
