Transcript Symbiosis

Symbiosis
A partnership between two
different organisms in nature.
Types of Symbiosis
• Mutualism
• Commensalism
• Parasitism
Mutualism
A symbiotic relationship in which
both organisms benefit.
Commensalism
A symbiotic relationship in
which one organism
benefits and the other
neither benefits nor is
harmed.
Parasitism
A symbiotic relationship in which
one organism benefits and the
other is harmed.
The Predator and Prey
relationship, is NOT
symbiosis.
Why?
For each of the following
slides, tell what type of
symbiosis.
mutualism
commensalism

Clown Fish and Anemone:
The anemone provides protection for the clown fish
The Tree Sloth has algae growing in its fur. These algae
help to camouflage the sloth against the lichen-covered
tree. There is even a moth that lives only in the sloth's fur
and consumes the algae.
Sharks and Remora
Bees and Pollen
Plaque is a sticky, colorless film of bacteria and sugars that
constantly forms on our teeth. It is the main cause of
cavities and gingivitis,
and can harden into tartar if not removed daily.
The flicker below has excavated its nest in the dead wood
of a living sycamore tree.
Barnacles on a Whale
The oxpecker is a bird that rides
around on the backs of cattle and other
large animals such as rhinos
The wasp above has stung and paralyzed a spider. It will
take the spider to a nest and lay an egg on it. The larvae
will consume the still-living spider; often from the inside.
Intestinal bacteria (normal flora)
and digestion.
The white-winged dove and the Sagauaro Cactus.
The cactus provides food for the bird in the form of a large
fruit. The bird consumes the fruit, also ingesting the cactus'
seeds. The bird then flies off and later deposits the seeds in a
new location.
The Sea Lamprey latches onto a fish and uses the teeth to
hold on and rasp away the skin, leaving an open wound for
the lamprey to feed on. It drops off, usually without killing
the "host".
The Hippos rely on the oxpecker bird to rid their bodies
of parasites and insects, as do the zebras, giraffes,
elephants and rhinos. The oxpecker, for his part, gets
an easy meal.
