Transcript What type of ecological organization do you see in the pictures?

Aim: How do organisms have
different roles in the
environment?
What type of ecosytem does
Nemo live in?
What ecological level is this?
Community
The different types of
populations in a given
amount of space.
Habitat
A specific area where an
organism lives
What is Nemo’s habitat?
Does everybody in a community have the
same job?

No, each
organism has its
own ROLE in a
community or
NICHE
What is the niche of a plant
population in a community?
To produce
food using the
energy from
the sun
 Producers organisms that
can make their
own food

What is the niche of herbivores in
a community?
To eat plants
 Primary Consumersanimals that eat
plants.

What is the role of carnivores in a
community?
To eat animals
 Secondary Consumerseat primary
consumers.

What is the niche of
bacteria & fungi?



To return nutrients
back to the soil by
breaking down dead
organisms
Decomposers –
breakdown dead
organisms
Bacteria & Fungi
(mushrooms).
Why are decomposers the
“Recyclers” of the ecosystem?
They break down dead
organisms & at the
same time return raw
materials back to the
ecosystem.
Nitrogen Cycle:
What is a scavenger’s niche?

To eat animal’s
that were killed
& leftover by
secondary
consumers
What happens if two organisms
occupy the same niche?


Organisms would compete
until the best adapted
population wins.
Organisms can sometimes
appear to occupy the same
niche, but under more
careful examination, they
do not.
