Find the sentence that tells the meaning of shelter.
Draw a line under the sentence.
All the living and nonliving things
around you make up your environment.
A living thing lives in the environment that
meets its needs.
Many animals need shelter. Shelter is
a place where an animal can be safe.

5. A jellyfish has body
parts that help it
catch its food.
Why do many plants
live in the top layer of
the ocean?
An ocean environment is a large body of
salt water. Its top layer is home to many living
things. Here, plants and other living things get
the sunlight they need. Animals can find food.
Kelp lives in the
ocean. Many animals
eat it.

6. A rain forest gets a lot of rain. The trees
grow tall and block the sun. Many animals,
such as birds and monkeys, use the tall trees
for shelter. The shorter plants do not need
much sunlight.

7. Desert plants and
animals can live with
little water.
A desert environment
gets little rain. Plants such
as cactuses store water in
their thick stems. Other
plants store water in their
leaves. In hot deserts, many
animals hide during the day.

Trace the arrows to show
the order of the food chain.
All living things need energy from the
sun. Plants use sunlight to make food.
Then animals eat the plants. They get the
energy they need from the plants.
A food chain shows how energy
moves from plants to animals.

Food Chain

The grass uses sunlight
to make food.

2-L clear plastic bottle with
cap, cut in half
potting soil
small plant
10 pill bugs
gloves
damp leaf cuttings
rotten vegetables
water
tape
Can animals get the
things they need from
their environment? Make
a terrarium to find out.
What Is a Terrarium?
Add damp leaf cuttings,
rotten vegetables, and a
cap of water. Then add
the pill bugs.
Put about 3 inches of soil
in the bottom of the bottle.
Place the plant in the soil.
Lightly water it.
Tape the bottle parts
together. Put it in a
cool, sunny place.
Observe the pill bugs
for one week. Record
your observations.
Lightly water it.
