Adaptations
• A characteristic that helps a living thing survive is called an
adaptation.

Unit 4 Lesson 6 What Are Physical and Behavioral Adaptations?
Adaptations
• Animals that survive better because of a new characteristic are
more likely to reproduce and pass that characteristic on to their
young.
• The adaptation becomes more common in the population. In this
way, populations of plants and animals become adapted to their
habitats.

Adaptations
• If animals have similar habitats, they share similar
adaptations.

Form and Function
• Physical adaptations are differences in the bodies of
organisms.
• Organisms have physical adaptations that help them
survive in different environments.

Form and Function
• When an organism has a characteristic that helps it
survive in a way that others cannot, the organism with the
adaptation has an advantage.

Eat or Be Eaten
• Some physical
adaptations protect
living things from
being eaten.
• Physical adaptations
that help to keep an
animal hidden are
called camouflage. For
instance, green lizards
in green grass are
camouflaged.
• Animals that hunt
have physical
adaptations that help
them catch food.

Eat or Be Eaten
• Plants have
adaptations that
help spread their
seeds.
• Some seeds can be
carried by the wind.
• Other seeds are
inside berries. Once
eaten, the seeds are
carried to a new
location.

On Your Best Behavior
• The way living things act is called behavior. Some
behaviors are adaptations that help animals survive.
• Behaviors that animals know how to do without being
taught are called instincts.

On Your Best Behavior
1. Migration occurs when
animals move to
different locations at
certain times of the
year to find food,
reproduce, or escape
cold weather.

2. Hibernation is a long period of inactivity that is like
sleeping. The body processes of hibernating animals
slow down, and the animals stay inactive for months.

same type is called social behavior.

The Circle of Life
• Living things go through stages of growth and
development called a life cycle.
• A living thing’s life cycle is related to its habitat. Because
of this, differences in life cycles are a type of adaptation.

Living Things Change
• Every organism is slightly different
from every other organism.
• For example, corn snakes come in
many colors and patterns. Their
survival can depend upon their
color and whether their predators
can see them.
• If the predator cannot see the
snake, they are more likely to
survive and produce more
offspring with the same coloring.

Living Things Change
• Sometimes living things change
because their environment
changes.
• For example, bacteria have
changed with the discovery of
antibiotics that kill them. The first
antibiotic, penicillin, saved lives.
• Some bacteria resist penicillin,
however, and survive and multiply.
Researchers must find new
antibiotics to kill the resistant
bacteria.
