R.P. Describe two different
organisms that depend on
each other for their survival.
What are these?
• S7L4d categorize relationships between organisms
This is another of our Georgia Performance Standards.

Does everyone know how to get to Daniell’s site?
Organisms’ Interdependence:
Cornell notes
• Cornell notes are a type of two column
notes.
• Questions are on the left and the major
notes are on the right side.
• You can write questions as you go, or as
you reread notes add questions.
Types of Questions:
What I still do not understand.
What else I’d like to know.
A good test question.
Lion King Video Clip
Pay attention to all the different animals and
plants that you see or hear.
On the left
Organisms in
list them here with commas
organism one, two, etc
Lion King:
Share your list with the person next to you.
Don’t write this.
How do the organisms interact?
• There are three main ways that organisms
interact. Some organisms pretty much are
dependent on another for survival.
•
Any ideas?

Describe how 1. Predation – relationship
where one animal hunts
Organisms
and kills for food.
Interact?
predator – organism that
kills and eats another.
predator adaptations –
speed, sharp teeth & claws.
ex. Lions
Coral snake
prey – organism that is killed
and eaten. (din din)
prey adaptations –
stay in groups, camouflage,
warning color, defensive
chemicals, shells
ex. Deer, turtles pg 492-493
Scarlet king snake
2. Competition – two or
more organisms trying
to use the same limited
resources.
ex. Squirrels and
chipmunks
ex. Plants competing
for sunlight p 491

3.
Symbiosis – a close long
term relationship
between two organisms
where at least one
benefits.
Don’t write this
Mutualism, commensalism
parasitism – sounds like?
a.
mutualism
–
both
benefit.
Describe the 3
types of
Symbiosis?
ex. Egret and rhino
3 types of
Symbiosis
continued
b. commensalism – only
one benefits; other is
not harmed or helped.
ex. Hawk and cactus
remora and shark
3 types of
Symbiosis
continued
c. Parasitism relationship
between two species in
which one species, the
parasite benefits from
the other species the
host which is harmed
ex flea (parasite) dog (host)
kudzu (parasite) oak tree (host)
P 495
What is
Coevolution?
Long term change that
takes place in two
species because of
their close interactions
with one another.
Ex ants and acacia
tree pg 495
What is a
population?
Number of one species
that lives in an area.
What are
limiting factors?
Food, water, living space
and other resources that
limit the size of a
population
What is the
The largest population an
Carrying capacity?
environment can
support.
Cornell Notes – Summary
do not write this page of notes
The professor at Cornell who is credited
with these notes learned that if he didn’t
make his college students stop, re-read
notes and summarize, these young adults
didn’t remember the material as well.
So, future college students, take a few
minutes to read over every word, then
write a summary in the summary section.
