This document defines key habitat and environmental science terms and provides examples of different habitats. It discusses what an environment and habitat are, as well as specific habitats like deserts, rainforests, forests, tundra, and freshwater and saltwater habitats. It also covers animal adaptations, how plants and animals interact in an ecosystem, and defines producer, consumer, herbivore, carnivore, and omnivore. Food chains are explained as the transfer of energy from plants through animal species.

2. What is an environment?
• Plants and animals live together in many
different environments all around the
world.
• An environment is all the living and
nonliving things in a place.
• The environment is the surroundings: air,
water, plants, and animals.
• Each kind of environment has many
different kinds of animal habitats.

3. What is a habitat?
• Every animal has a
habitat.
• The place where an
animal or plant lives
and grows is called its
habitat.
• A habitat is where an
animal finds the food,
water, and shelter it
needs to live.
• For example, a toucan’s
habitat is the rainforest.

5. Desert Habitats
• A desert is a very warm place. The air is very hot and dry.
• There is very little rain. The soil is very sandy.
• Most animals that live in the desert sleep during the day
because it is too hot. They come out at night to eat. They
are called nocturnal.
• Some desert animals burrow in the ground during the day
• Many plants have thick leaves in the desert to retain
water.
• Most desert animals get their water from the food
they eat.

6. Rain Forest Habitats
• A rain forest is an
environment where rain falls
almost every day.
• A rain forest has warm
weather year round.
• A rain forest has millions of
plants and animals.
• Many of these plants are used
to make medicines to fight
diseases and illnesses.
• Rain forests are located along
the equator.

7. Forest Habitats
• A forest is an
environment that
gets enough rain and
warm temperatures
for lots of trees to
grow.
• When the fall arrives,
the leaves will turn
red, orange, and
yellow.
• Once winter comes,
the trees lose their
leaves.

8. Tundra Habitats
• A tundra is an environment
that is very cold and windy.
• It is a treeless area.
• It is the coldest environment.
• The land is covered with
snow and ice most of the
year.
• Much of the land has
ground that is permafrost,
permanently frozen.
• The summers are short.

9. Freshwater Habitats
• Pond
• Lake
• Stream
• River
You might find frogs, ducks, beavers,
turtles, dragonflies, and many kinds of
fish in a freshwater habitat.

10. Saltwater Habitats
• Oceans
Sharks, starfish, whales,
dolphins, lobster, and coral
are some of the animals
found in the ocean.

11. Animal Adaptations
• Camouflage
• Migrate
• Body Coverings
• Hibernate
• Estivate
• An adaptation is anything about an animal that helps it
live or survive in its environment.
• Animals are always in danger of being eaten and have
developed many ways of protecting themselves from
hungry animals.
• Animals may find winter shelter in holes in trees or logs,
under rocks or leaves, or tunnel underground.
• If animals do not adapt to their environment, they die!

12. Camouflage
• Camouflage is when the animal
blends in with the surrounding
environment to help it hide.
• Some animals’ fur or skin can
change color. This helps to
protect them.

13. Some Animals Migrate
• Some animals travel to far away places. This is called
migration.
• Animals move from one habitat to another to survive.
• Animals are looking for warmer weather or searching for
food.
• Many birds migrate in the fall. Birds can fly very long
distances.
• Many fish migrate. They may swim south, or move into
deeper, warmer water.
• Many insects also migrate.
• Whales, butterflies, bats, hummingbirds, robins, geese,
ducks, salmon are some animals that migrate.

14. Body Coverings
• Some animals will grow new, thick
fur in the fall to keep warm in the winter.
• An armadillo has a covering of hard plates to
protect its body.
• The porcupine uses its quills for defense.
• A turtle can pull its head, feet, and tail inside its
shell for protection.

15. Some Animals Hibernate
• Hibernation is when an animal goes through the winter into
a long, deep sleep.
• One way animals can adapt to the changing environment is
by hibernating.
Some animals hibernate for part or all of the winter. The
animal's body temperature drops, and its heartbeat and
breathing slow down. It uses very little energy. In the fall, these
animals get ready for winter by eating extra food and storing it
as body fat. They use this fat for energy while hibernating.
Some also store food like nuts or acorns to eat later in the
winter. Bears, skunks, chipmunks, and some bats hibernate.
Insects look for winter shelter in holes in the ground,
under the bark of trees, deep inside rotting logs or in any small
crack they can find.

16. Some Animals Estivate
• Estivate is when an animal sleeps during the
summer.
• What causes an animal to estivate? HEAT
• Ground squirrels in the desert will estivate in their
burrows to get out of the heat.
• Some toads estivate to escape the hot, dry summer.
• Many amphibians and reptiles estivate, as do some
insects, snails, and fish.

17. How do plants help animals?
• Plants provide food and shelter for many
animals.
• Plants are used to make medicines to fight
disease and illnesses.
• Animals use plants for shelter. For
example, birds build nests and beavers
build dams.
• Plants provide oxygen that we need to live.
• Plants provide protection for animals
hiding.
• Plants are used to make clothing, paper,
and wood products.
• Plants also provide beauty for the Earth.

18. How do animals help plants?
• Animals help spread seeds.
• Some animals, like
squirrels, bury seeds when
they store them and forget
to go back to get them.
Some of these seeds that
are left in the ground will
germinate.
• Seeds attach to animals
that have fur. Later the
seeds will fall off the animal
and grow in a new place.
• Insects and birds help
pollinate flowers.

19. Ecosystem
• An ecosystem is how plants, animals,
and nonliving things in an environment
effect each other.

20. Herbivores
Some animals do not eat other animals.
They survive on plants and are known as
“herbivores”.

21. Carnivores
Some animals, like the kingfisher, eat
only other animals. These animals are
called “carnivores”.

22. Omnivores
• Some animals, like us, eat both plants
and animals.
• These animals are called “omnivores”.

23. Producers
• Plants are living organisms. They need
nourishment to survive.
• But…
• Plants do not eat other plants or
animals.
• Plants are called producers, because
they produce their own food using
sunlight.

24. Consumers
• “Consume” means “eat”.
• Animals are consumers because they
“eat” (consume) food provided by plants
or other animals.

25. What is a food chain?
• Food chains show how each living thing gets its food.
• A food chain is the order in which animals eat plants
and other animals.
• The sun is the primary source of a food chain. Plants get
their energy from the sun. Without the sun, we would not
have any plants. A food chain always starts with a plant.
• Next in the food chain is an animal, because plants
cannot eat plants.
• A food chain always ends with an animal.
