Mutualism
A relationship
in which
both species
benefit.
This little fish is
helping me by
cleaning my
teeth!!! Yeah!!!
I’m eating the big
fish’s food so
he’s helping me
too! Yeah!!!
Commensalism
A relationship in
which one
species benefits
and the other
species is
neither harmed
nor benefited.
In this picture, Spanish moss is
growing on the trees. The moss
benefits because it has a place
to live, and the tree doesn’t care.
Parasitism
A relationship in which one species
benefits and the other species is
harmed.
Tapeworms are
parasites.
They attach to your
intestines
and suck out all of
your food.
the tapeworm
benefits, and
the host is harmed
because they
slowly starve to
death.
Parasitism
Parasites have evolved in such a way that
they harm, but usually do not kill the host
species.
One of the ways to get rid of a
tapeworm is to starve yourself and
then place a piece of meat in front
of your mouth. The tapeworm will
smell the meat and climb up your
throat and out of your mouth.

egret rides on the back
of large mammals like
elephants. The egret
benefits because it gets

fungi attaches the organism to the tree and
protects the algae. The algae provides food
through photosynthesis.
