Create Your Symbiosis Foldable
1. Fold your colored paper into thirds
(pamphlet fold or tri-fold).
2. Write “Types of Symbiosis” at the top of the
front cover of your pamphlet.
3. At the bottom of the front cover write
“Symbiosis is” and leave space for a
definition.

Objectives today!
• What is symbiosis?
• Compare and contrast the different
types of symbiosis?
• Be able to read examples and state
symbiosis type.

TYPES of SYMBIOSIS
Mutualism
both
organisms
benefit
Commensalism
Parasitism
one
organism
benefits
one
organism is
unaffected
one
organism
benefits
one
organism is
harmed
Example 1:
Acacia plant with ant galls
Ants lay
eggs on
acacia tree
Acacia
covers the
infected
area with
brown flesh
Parasitism: one
(gall)
benefits, one is harmed
Example 2:
Moray Eel with
Cleaner Fish
Moray Eel gets a
clean mouth and
Cleaner Fish gets
a meal!
Mutualism: both
benefit
Example 3:
Cattle with cattle egrets
Cattle stir
up insects
as they eat
grass
Egrets
hang
around and
eat insects
Commensalism: one benefits,
one is unaffected
Example 4:
Clown fish with anemone
Clown fish
gets
protection
Anemone is
unaffected
Commensalism: one benefits,
Example 5:
Antelope with Oxbird
Antelope
gets rid
of
parasites
Oxbird
gets a
meal
Mutualism: both benefit
Example 6:
Taenia worm in human eye
Worm
infects
human
blood
stream
Human
may go
blind Parasitism: one benefits,
one is harmed
Assignment
• On the next clean page in your IAN, Write the
3 types of Symbiosis, leaving 5 lines beneath
each one.
• For the remainder of class, write down 5
examples of EACH TYPE of symbiosis
underneath the type name. Must be
relationships of organisms you have seen in
your life.
