SPI 0807.5.2 Adaptations
Notes
Science
Tennessee SPI Objective Analyze structural,
behavioral, and physiological adaptations to
predict which populations are likely to survive
in a particular environment.
Instructions for Students 1) Make sure you view
this presentation in slideshow mode. 2) If you
need help, please communicate with your teacher.
3) If needed, there are videos about how to do
this on YouTube.
Essential Question How do species adapt their
behavior and their physical structure in order to
survive?
Check for Understanding Identify an organisms
adaptations that enable it to survive and/or
thrive in a specific environment.

Definition To adapt means to change in order to
survive and/or thrive in a specific environment.
Two types of adaptations 1) Behavioral 2)
Structural
what an organism does
concerns the shape and form of the body
Can you see them?
Question See the insects in the picture below?
Is this mainly behavioral or structural
adaptation?
This is called camouflage
This is mainly structural adaptation because
these insects have adapted by developing bodies
that look like thorns.

Two types of adaptations 1) Behavioral- what an
organism does 2) Structural- concerns the shape
and form of the body
Look at the image of the hibernating bear
Question Is this a mainly a behavioral or
structural adaptation?
This is behavioral because it is an action that
the animal does.

Two Key Behavioral Adaptations

requires 2 parents (male and female)
1) Sexual Reproduction
Advantage Genetic diversity which results in
greater adaptability Disadvantage Large amount
of time and effort to find a mate Advantage No
time and effort needed to find a
mate Disadvantage Lack of genetic diversity
which results in less adaptability
requires only 1 parent
2) Asexual Reproduction

Notes
1) When environmental changes occur
organisms must change (adapt) by either changing
their behavior or changing their body structure
or both.
2) The process that drives this
is called natural selection.
3) Changes and variations in populations result
from
sexual reproduction (over many generations) and
changes in the environment.
4) Changes and variations also result from
genetic mutations (over many generations) and
changes in the environment.
