SYMBIOSIS
How are our relationships
comparable to ecology?
What is symbiosis?



Symbiosis: is a close
ecological relationship
between the individuals
of two (or more) different
species.
Mutualism: cooperative
relationship in which both
species derive some
benefit.
Example: Pollination




Parasitism: one individual
known as the parasite,
feeds on another
individual, known as the
host.
Endoparasite- Internal
Ectoparasite- External
Commensalism:
interaction in which one
species benefits and the
other is not affected.
Objectives

1. To explain that all things have relationships.
2. To go into detail of Symbiosis:

Parasitism
Commsensalism

Mutualism

How do we understand Symbiosis?

Every ecosystem has
many different
symbiotic
relationships. Each
fills a niche. All
symbiotic
relationships are
specific to the
organisms. You can’t
replace one with
another.

Dog
Fleas
Heart Worm
Giardia
Commensalism
1.
An orchid lives on a
tropical tree. It lives
on the tree to reach
the sunlight.
Mutualism
1.
There is a bird, the Egyptian plover, which
cleans crocodile teeth by eating the left over
food particles in the crocodile’s mouth.
So what do my relationships have
to do with ecology?



Ecology is all about the relationships
within an ecosystem.
If the relationships work well the
ecosystem is healthy.
We all have relationships if they are
healthy we are vibrant, productive, happy
and fulfilled!
