Desert Plants
Many plants are found in the desert.
They usually grow close to the ground.
These plants have special parts that help
them save water.
The special parts are: thick stem, shallow
and wide roots, and thick skin covered
with spines instead of leaves.
Desert Animals
There are many animals in the desert.
They can survive by eating other animals or by
eating plants that store water.
To protect them from the hot sun, they stay in
the shade or in their shelter.
Animals may build their shelters inside plants.
Some animals sleep during the day and are
active at night.
Some animals have hard shells to protect them
from losing much water.
More animals live in hot deserts than in cold
deserts.
