1. Adaptation- a characteristic that helps an organism survive in its
environment.
2. Camouflage- an adaptation by which an animal protects itself against
predators by blending in with the environment.
3. Mimicry- an adaptation in which an animal is protected against
predators by its resemblance to another unpleasant animal.
4. Protective coloration- a type of camouflage In which the color of an
animal helps it blend in with its background, protecting the animal
against predators.
5. Protective resemblance – a type of camouflage in which the color,
shape, and texture of an animal blends in with its background,
protecting it against predators.
Notes
1. Adaptations are important to organisms because successful adaptations
help organisms survive in their environment.
2. Organisms inherit adaptations from their parent or parents when they
reproduce.
3. There are two kinds of adaptations.
a. Structural adaptations- are adjustments to internal or external
physical structures that help an organism survive in certain
environments. It deals with the organism’s structure. These

adaptations can also protect the organism or enable it to hunt more
successfully.
Examples: fur color, long limbs, strong jaws, web feet, scales, and the
ability to run fast
b. Behavioral adaptations- are adjustments in the organism’s
behavior. An organism’s response to its environment. It is how the
organism acts or behaves.
Examples: woves traveling in a pack, migration, herd of animals,
hibernation
Migration- is a movement of animals to find food, reproduce in better
conditions, or find a less severe climate.
Examples of animals that migrate: birds, butterflies, fish, mantees
Hibernation- is a period of inactivity during cold weather.
Example of animals that hibernate: bats, snakes, frogs, bears
Plant adaptations help plants get food and water and reproduce in
their environment.
Stomata are tiny pores on the leaves of plants where important gases
enter and leave the plant.
Some plant adaptations:
a. Scented flowers to attract pollinators
b. Leaves that catch sunlight
c. Roots soak up water
d. Pseudobulbs or “ false bulbs” which are storage organs(orchids)
e. Thick, waxy stems to prevent water loss (cactus)
