Transcript Presentation Ecologial Relationships

Producers
• Green plants
• Because green
make their own
plants use the
food and are
energy of the
thus the food
sun to make
producers of
their own food
the ecosystem.
they are called,
autotrophs.
Consumers
• An organism • Consumers
that feeds
are also
directly or
called
heterotrophs
indirectly on
producers is
called a
consumer.
Consumers
Are these examples of high level consumers?
If not, what are they considered?
No, cows and goldfish are primary
consumers.
Which of these
organisms is a primary
consumer?
Are most
humans
carnivores,
omnivore or
herbivores?

What shape are the bacteria below; rod, spiral
or sphere?
Competition
• When there is only
a limited amount of
food, water, shelter,
or even light in an
environment,
competition
occurs.
• Competition is a
type of relationship
where organisms
struggle with one
another and their
environment to
obtain the materials
they need to
survive.
Competition
What resource are these wildebeest and elephants competing for?
What resource is an issue in these
photos?
Space and light
Symbiosis
• Symbiosis is a
relationship in
which one
organism lives on
or even inside
another organism.
• This relationship may
benefit one or both
organisms or may
harm one.
What does this alligator get
from the butterflies?
Predation +/• A predator is an
animal that kills and
eats other animals.
• The animal that is
killed is the prey.
• The relationship
between these
two animals is
known as
predation.
Which organism is the
predator which is the prey?
Can you think of a few other
predator prey relationships?
Predator- Prey Video
• YouTube - Air Jaws Super Slow
Parasitism +/• In the relationship
called parasitism,
one partner does
not benefit and is
actually harmed by
the other organism.
• The organism that
benefits is the
parasite.
• The organism the
parasite lives off of
and harms is called
the host.
A few examples…
Some beautiful
parasites, huh?
What do you think will happen to
these hosts?
Botfly Video
• Maggot
Mutualism+/+
• A symbiotic
relationship
that is helpful
to both
organisms is
called
mutualism.
• Food and
protection are
two common
reasons
organisms
share such a
partnership.
Can you think of any mutualistic
relationships?
Check out a
few forms of
mutualism in
the ocean!
How is the flower benefiting?
What does the
bee get out of
the
relationship?
Communalism +/0
• A symbiotic
relationship in
which only one
organism in the
partnership
benefits is called
communalism.
• The other
organism in the
relationship is
neither helped
not harmed.
Which organism is not being
helped nor harmed?
How could this birds large nest
help smaller birds?
Is this communalism?
Ecological Succession
• When in nature, one community is
replaced with a larger and bigger one.
• Pioneer Organisms – first things to
populate an area.
• Climax Community – the largest
community that will keep going until a
catastrophic change happens.
