Symbiosis
A relationship where two
organisms (of different
species) live together.
There are 3 symbiotic
relationships:
• Mutualism:
– A relationship where both species benefit.
• Commensalism:
– A relationship where one organism benefits
and the other does not benefit and is not
harmed.
• Parasitism:
– A relationship where one species harms the
other species.
Examples of Mutualism:
• Termites and Bacteria
in intestines
– Bacteria live in
intestines
– Break down cellulose
– Bacteria digest wood.
Examples of Mutualism:
• Rhino and Tick Bird
– Tick bird eats ticks off of
rhino—YUMMY!
DINNER!
– Tick bird warns of
danger by making noise.
– Tick bird eats ticks
which can be parasites to
the rhino
Examples of Mutualism:
• Bees and Flowers
– Bees use the pollen and
nectar to make honey
– Flowers need the bees to
help the plant reproduce.
– They both benefit!
Examples of Commensalism:
• Clownfish and Sea
Anemones
– Clownfish live in
anemones; this gives
them protection
– Clownfish have a
protective coating on
scales that prevent them
from getting stung.
– Sea anemones do not
benefit.
Examples of Parasitism:
• Tapeworm in Human
– Tapeworms live in the
intestines of humans and
consume materials the
host (the human) need!
– Tapeworm thrives, the
human is harmed.
Examples of Parasitism:
• Tick on Dog
– Ticks attach themselves on
to the skin of a dog. The
ticks suck the blood of the
dog and can transfer
diseases.
– Tick thrives, the dog is
harmed.
