9. Symbiotic
Relationships

10. Symbiotic Relationships
 symbiosis - the relationship between two
different individual species that live together
in a close relationship (living together)
 The word symbiosis can be broken down
into two parts to determine its meaning
 sym means together
 bio means life

11. Types of Symbiosis
 There are three
types of symbiotic
relationships
 Mutualism (+, +)
 Commensalism (+, 0)
 Parasitism (+, -)
 Each relationship
can be shown using
+ , - , or 0

12. Mutualism  mutualism - a
relationship where
both organisms
benefit
 A + / + relationship
 Think of a normal
friendship where
both friends gain
something from the
friendship
The acacia galls are homes to stinging
ants and the ants defend acacia from
other insects that would harm tree
leaves.

13. Mutualism
Flowers and their Pollinators
(Example: Bees and hummingbirds gather nectar and spread pollen.)

14. Mutualism
The moray eel
gets a clean
mouth and the
cleaner fish gets
a meal.

15. Mutualism
Birds and mammals eat berries and
fruits while the plant benefits by
the dispersal of it seeds.

16. The oxbird
gets rid of
the
parasites
on the
antelope
and allows
the oxbird
to have a
meal.
Mutualism

17. Mutualism
Cleaners eat insect pests from the
skin of animals.

18. Mutualism
Algae and Fungi (Lichen) - Alga
gets water and nutrients from
the fungus and the fungus gets
food from the algae.

19. Mutualism
Many herbivores such as cows, sheep,
deer, horses and rabbits depend on
bacteria that live in their stomachs to
break down the plant material.

20. Mutualism
The corals get food and the
algae are protected.

21. Commensalism
 commensalism – a
relationship where one
species benefits while the
other species remains
unaffected
 A + / 0 relationship
 Think of a friendship
where one of the friends
benefits while the other
doesn’t change

whale

22. Commensalism
One species uses a second organism
for housing such as small mammals
or birds that lives in holes in trees or
orchids which live in trees.

23. Cattle stir
up insects
as they eat
grass and
the
egrets
hang
around and
eat insects.
Commensalism

24. Commensalism
Clown fish get
their protection
from the sea
anemone and
the anemone is
unaffected.

25. Commensalism
Shark eats
and the
remora gets
the scraps
left by the
shark.

26. Parasitism
 parasitism – a relationship
where one organism
benefits (parasite) while the
species it depends on (host)
is harmed
 host – an organism on
which a parasite lives
 A + / - relationship
 Think of a friendship where
you might feel used by your
friend
Parasitic isopod on fish

27. Parasitism
Ticks and fleas that live in a host
animal's fur bite the animal and
drink its blood are parasites.

28. Parasitism
Mistletoe takes
moisture and
nutrients from the
plant while the
woody plant has
to support itself
and the
mistletoe.

29. Parasitism
Insects such as mosquitoes
feeding on a host are parasites.

30. The tick eats
the blood of
a human
and the
human
receives
Lyme
disease from
the tick.
Parasitism

31. Parasitism
Vines such as Kudzu growing on Trees

32. Parasitism
Tomato Hornworm with Wasp Eggs

33. Parasitism
The tapeworm
attaches itself
to the intestines
of a dog and
the tapeworm
takes nutrients
from the dog.

34. Parasitism
Tapeworm or Hookworms living in
Host's Gut

35. LET’S HAVE A RECAP:
WHAT IS SYMBIOSIS?
it means:
Two organisms that live together
Temporarily or for a longer time
At least one of the organisms
benefits from the relationship

36. What are the different kinds
of symbiosis?
Mutualism Parasitism
Commensalism
both organisms
benefit
one organism
benefits
one organism
benefits
one organism
is unaffected
one organism
is harmed

37. Mutualism
Organism One Organism Two

38. Commensalism
Organism One Organism Two

39. Parasitism
Organism One Organism Two

40. Acacia Plant & Ants
The ants lay eggs on
acacia tree so they get
a nice safe place for
their eggs. The acacia
covers the infected
area with brown flesh
(called a gall.) The
plant has to use
valuable resources to
create the gall.
What symbiotic relationship is
this?
parasitism

41. Anemone & Anemone Fish
mutualism
This fish lives its entire adult life
among the tentacles of a bulb-
tentacle sea anemone. Anemone fish
do not get stung by the anemone as
would most other fish so they get
protection from predators. The fish
often drop food scraps which the
anemones can eat.

42. Boxer Crab & Anemones
This Boxer Crab carries a
pair of stinging anemones
in its claws, which it uses
to defend itself from
predators. The anemones
get to move around which
increases their food
supply.

43. The remora attaches itself
to the shark and saves
energy since it doesn’t
have to swim, and it gets to
snack on the sharks kills.
The shark doesn’t get
anything.

44. This tiny emperor shrimp is
riding along on the back of a
sea cucumber (a long worm-
like starfish relative) while it
crawls along a sandy bottom.
The shrimp gets to travel
around under the protection of
its much larger partner, and
the sea cucumber doesn't
seem to mind.

45. Moray Eel & Cleaner Fish
This moray eel has a small fish
cleaning between its teeth. The
eel gets a clean mouth while the
cleaner fish gets a nice meal.
What symbiotic relationship is
this?
mutualism

As these cattle walk
around eating grass they
stir up lots of insects. The
egrets hang around and
get a yummy meal of
insects.
What symbiotic relationship is
this?
commensalism

unaffected.
What symbiotic relationship is

of bugs living on
the antelope. The
antelope gets rid
of parasites.
What symbiotic relationship is
this?
mutualism

49. Loa Loa Worm & Human
This worm infects
the human blood
stream and gets a
nice warm safe
home there. The
human may go
blind or have other
complications as a
result.
What symbiotic relationship is
this?
parasitism

50. Goby and Alpheid Shrimp
What symbiotic relationship is
this?
mutualism
This alpheid shrimp (on
the right) uses its
strong claws like a
bulldozer to create a
burrow in the sand.
The shrimp is nearly
blind. It relies upon its
partner, the sharp-eyed
goby, to warn of
danger. When a
potential predator
approaches, both
animals disappear
quickly into the burrow

51. Wrasse & Batfish
Can you see the two
cleaner wrasses are
removing parasites from a
batfish? One of the wrasses
has entered the gill slit of
the batfish, and may even
enter its
mouth in search of food.
The batfish gets a bath and
the wrasse gets a meal.
What symbiotic relationship is
this?
mutualism
