SYMBIOSIS is the interaction between 2 different organisms
where at least one benefits HOST- usually the LARGER of the 2
organisms SYMBIONT- usually the SMALLER member

Slide 5
PARASITISM Is a relationship where the Symbiont lives in/on the
Host The Symbiont (or Parasite) BENEFITS The Host is HARMED For
example, the tick in the picture above is a parasite. It benefits
by extracting blood from its human host. The human is harmed.
EXIT
Slide 6
Is a relationship between the host and a symbiont, 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. Mutualism EXIT

Slide 8
COMMENSALISM Is a relationship between the host and symbiont,
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. EXIT

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 PARASITISMMUTUALISMCOMMENSALISM

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 relationship is an example of EXIT PARASITISM MUTUALISM
