This document discusses various types of adaptations that help organisms survive in their environments. It describes structural adaptations like teeth, shells, and camouflage. Behavioral adaptations include innate behaviors, learned behaviors, and seasonal behaviors like migration and hibernation. Physiological adaptations are controlled by the brain and include temperature regulation. The document explains how genetic variations within populations and natural selection leads to survival of the fittest as traits better suited for the environment are passed on.

1. Adaptations

2. Objectives
 SPI 0807.5.2 Analyze structural, behavioral, and
physiological adaptations to predict which populations are
likely to survive in a particular environment
 SPI 0807.5.3 Analyze data on levels of variation within a
population to make predictions about survival under
particular environmental conditions.
I can:
 Identify an adaptation as structural, behavioral, or
physiological.
 Explain how an adaptation helps an organism survive in a
particular environment.

3. Types of Adaptation
 Anything that helps an organism survive in
its environment
 Adaptations are inherited from their parents
 It also refers to the ability of living things to
adjust to different conditions within their
environments.
 Structural adaptation
 Behavioral adaptations
 Physiological adaptations
I can identify an adaptation as structural, behavioral, or physiological.

4. Structural adaptations
 A structural adaptation involves
some part of an organism's body.
 Teeth
 Body coverings
 Shells
 Quills
 Scales

 Mimicry
I can identify an adaptation as structural, behavioral, or physiological.

5. Example of Adaptation
 The shape of an
animal’s teeth is
related to its diet.
 Herbivores, such as
deer, have many
molars for chewing
tough grass and
plants.
 Carnivores, such as
lions, have sharp
canines to kill and tear
meat.
I can explain how an adaptation helps an
organism survive in a particular environment.

6. Camouflage
 Camouflage allows
an animal to blend
into its environment.
 Makes it hard for
enemies to single out
individuals
I can explain how an adaptation helps
an organism survive in a particular
environment.

7. Mimicry
 Mimicry allows one
animal to look,
sound, or act like
another animal to fool
predators into
thinking it is
poisonous or
dangerous.
I can explain how an
adaptation helps an
organism survive in a
particular environment.

8. Plant Adaptations
 Vascular-stems
 Root systems
 Thorns
 Leave type
 Broad:absorb more
sunlight
 Small needle-like:
reduce water loss

loss, protect from
fire
 Poisonous/toxins
I can explain how an adaptation helps an organism survive in a particular environment.

9. Behavioral adaptations
 Behavior adaptations
include activities or
behaviors that help an
animal survive.
1. Innate
2. Learned
3. Survival
4. Seasonal
I can identify an adaptation as structural,
behavioral, or physiological.

10. Innate vs. Learned
Innate
 Inherited through the
genes
 Examples
 Flying for bees, birds
 Swimming for fish
 Walking for humans
 Speaking for humans
Learned
 Learned from
experience or from
observing other
animals
 Examples
 Type of language
spoken for humans
 Riding a bicycle
I can explain how an adaptation helps an
organism survive in a particular
environment.

11. Survival Behavior
1. Finding food
 Predator-Prey adaptations
 Predator-animals that eat other animals
 Prey-animal being eaten
2. Marking Territory
 Way that animals inform other animals that an area is
occupied
3. Defensive Action
 Protect resources, themselves, food, mates, offspring
4. Courtship
 Behaviors used to find a mate
5. Parenting
 Depend on parents for survival
I can explain how an adaptation helps an
organism survive in a particular
environment.

12. Animal Defense
 Some animals use these
methods of defense to
protect themselves:
 Camouflage
 Snake
 Mimicry
 Mexican Milk Snake
 Bright colors
 Skunk and Poison
Arrow Frog
 “Hair” projections
 Hedgehog quills
 Deer Antlers
I can explain how an adaptation helps an organism survive in a particular
environment.

13. Seasonal Behavior
 Help organisms adapt to the
environment
1. Migration
2. Hibernation
3. Estivation
4. Biological Clock
I can explain how an adaptation helps an
organism survive in a particular
environment.

14. Migration
 Animals migrate for
different reasons.
 better climate
 better food
 safe place to live
 safe place to raise young
 go back to the place they
were born.
 Adaptation that
involves an animal or
group of animals
moving from one
region to another and
then back again.
I can explain how an adaptation helps an
organism survive in a particular
environment.

15. Hibernation
 Period of inactivity in which animal’s body
temp., heart rate, and breathing rate slow
down to conserve energy.
 Bats, woodchucks & bears.
I can explain how an adaptation helps an organism survive in a particular
environment.

16. Estivation
 Period of inactivity in the summer
 hot, dry places
 Snakes, lizards, frogs, toads
I can explain how an adaptation helps an organism survive in a particular environment.

17. Biological Clock
 Internal control of animal’s natural
cycle
I can explain how an adaptation helps an
organism survive in a particular
environment.

18. Physiological Adaptations
 Behaviors controlled by the brain
 Reflexes
 Blinking
 Pain
 Swallowing
 Tolerance to a certain poison
 Logical thinking
I can identify an adaptation as structural, behavioral, or physiological.

19. Mammals
 warm-blooded
 All have some type of
“hair”
 Some are very
specialized, such as
white polar bear fur
 Care for young
I can explain how an adaptation helps an
organism survive in a particular
environment.

20. Birds
 Leg Length
 Roseate Spoonbill
(top right)
 Foot Webbing
 Laughing Gull (top
left)
 Beak Shape
 Long Billed Curlew
(bottom)

organism survive in a particular
environment.

21. Reptiles
 cold- blooded
 Scales
 Some undergo
hibernation and
estivation
 Lay eggs on land
 Leg structure and
position

helps an organism survive in a
particular environment.

22. Amphibians
 Cold-blooded
 Lay eggs in water
 Partially of fully
webbed feet
 Have lungs or can
absorb oxygen through
their skin

organism survive in a particular
environment.
