Title: Ecological Relationships
Standard: Interpret relationships,
including predation, parasitism,
commensalism, mutualism, and
competition among organisms
EQ: How can I tell the difference
between the ecological relationships?
Title your paper “Ecology Quiz” – Number a Sheet of paper
1-10. Write out letter and answer.

A region of Earth with a specific climate and organisms
a.
adapted to the particular environment
2. Part of the earth’s surface that includes land, water, and b.
atmosphere where living organisms exist
c.
3. All of the interacting species within a particular ecosystem
4. Heterotrophic organisms that must consume other
d.
organisms for survival
e.
5. Living organisms that break down organic matter, making
it available to primary producers
f.
6. An organism that feeds on dead or decaying plant or
g.
animal remains

P- Take notes and raise your hand to ask
questions if you need to.
Remember: Resources are things organisms need to
survive.
• Resources can be biotic. • Resources can be
abiotic.
Adaptations and available resources
affect the relationships between
organisms in an ecosystem.
The three types of community interactions that can
affect an ecosystem are:
• Competition
• Predation
• Symbiosis
Competition: when organisms attempt to
use the same ecological resource
Organisms can compete for any resource:
•
•
•
•
•
Water
Food
Light
Mates
Habitats
Remember that resources are limited!
Predation: one organism captures and
feeds on another organism
Predator: kills and eats another
Prey: gets eaten
Both predator and prey affect the
other’s population.
• When the predator population goes UP, the prey
population will go DOWN (because they’re being
eaten).
• When the prey population goes DOWN, eventually
the predator population will go back DOWN (because
they’re running out of food).
• When the predator population goes DOWN,
eventually the prey population will go back UP
(because they’re not being eaten as often).
• When the prey population goes UP, eventually the
predator population will go back UP (because there is
more food available).
Symbiosis: Any
relationship in which two
species live closely
together
Symbiosis literally means
“living together”.
There are three symbiotic
relationships in nature:
Mutualism: both species benefit from the
relationship
 
Commensalism: one organism benefits while
the other is neither helped nor harmed

=I
Parasitism: one organism lives on or in another
organism and harms it
One is helped,
one is harmed


Parasite: the organism
invading the other; gets
its nutrients from the
host
Elephantiasis tropicablocks the lymph
vessels
Host: the organism
invaded by the parasite
Eco Relationships “Instas”
• Fold your paper so you create
4 boxes.
• In each box, draw an “insta”
for each type of ecological
relationship (Think about how
Instagram works…the picture
should describe the
relationships)
• Include a caption that also
describes the relationship
