SYMBIOSIS
Living things live
together in
relationships called
symbiosis.
SYMBIOSIS
 There are three types of symbiotic relationships.
At least one organism will benefit in all types of
symbiosis
1. Parasitism
2.Mutualism
3.Commensalism
Parasitism
 A symbiotic relationship where one organism
benefits from the association and the other is
harmed. The organism that benefits is called the
parasite, and the organism that is harmed is
called the host.
 It is different from a predator, because it
usually does not kill the organism it feeds
on.
 Examples: Fleas, leeches, worms, mites
Parasitism
Mutualism
 A relationship in which both species benefit.
 From the Desert Giant, the relationship between the saguaro
and the long-nosed bat is an example of mutualism.
 As you sit in this classroom,You are also participating in
mutualism…
Mutualism
 At this very moment, you are in a mutualistic
relationship with a population of bacteria in your large
intestine. Escherichia coli lives in most mammals to break
down food that mammals cannot digest. Bacteria gets
food and a place to live and we benefit as well!
Mutualism
Commensalism
 A relationship in which one species benefits and the other
species is neither harmed or helped.
 Example: Elf owl creating small hole for nest in the cactus.
Commensalism
