PARASITISM
Is a relationship where the parasite HARMS the host
For example, the tick in the picture above is a parasite. It
benefits by extracting blood from its human host. The human
is harmed because
EXIT
Mutualism
Is a relationship between two species,
where both organisms benefit and
neither is harmed.
The relationship can be long or short
term.
For example, in the photo above, the
host flower benefits by being
pollinated by the traveling butterfly.
The symbiont butterfly benefits from
the nectar that it extracts from the
flower.
EXIT
COMMENSALISM
Is a relationship two species, where the symbiont
benefits and the host is neither helped nor harmed.
The symbiont benefits by receiving transportation,
housing, and/or nutrition.
For example, in the photo above the symbiont
barnacles receive transportation from the host whale.
The host whale is neither helped nor harmed by the
barnacles.

EXTRA PRACTICE
ACTIVITY
In the following activity, you will be given a picture scenario.
Identify and select the symbiotic relationship (parasitism,
mutualism, or commensalism) represented in the picture.

In this photo the “cleaner fish”
receives nourishment by dining
off of the parasites and
remaining food debris in the
eel’s mouth. Is this an example

Clownfish are frequently found in
the tentacles of sea anemones. Sea
anemones capture their prey by
paralyzing them with their
tentacles. However, the clownfish
produces a mucus that prevents
the tentacles from harming it. By
dwelling amongst the tentacles the
clownfish receives a protected
home. This relationship is an
example of …

Lampreys are primitive fish with
limited digestive systems. They
attach to and feed on the body
fluids of fish with more advanced
digestive systems, often leading
to the death of the host fish. This

Orchids grow on the branches
of high trees. These orchids
get more water and sunlight
than those on the ground. The
tree is unaffected by the
orchid’s presence. This
