All animals have things they need to survive. If
an animal does not have these things it will die.
Like animals, people have needs. Let’s think
about what you need to survive. Not what you
might like to have, but those things you
absolutely must have.Without these things, you
could no longer live, you would die.
From the following, which things do you need to
survive? Not what you like or enjoy—what you
None of these are things the you need to
survive. These are things you might like to have
but not having them wouldn’t cause you to die.
Of course you would not die because you
did not have a television, video game, a
washing machine, a bed, and so on.
So let us look at those things that you really
do need to survive.
Try holding your breath.
Can you do it for ever?

On a hot day in summer
when you have been
running around outside,
you really notice another
thing that you need to
survive. What is it?
Yes, water is another
one of your needs.
Around lunchtime, you

feels like this.
What need could
be causing that?
Yes, when you need food you
feel hungry and when you feel
hungry it is hard for you to pay
attention to school work.
We must eat food to have
the energy to do things,
like playing or schoolwork.
People can go days, even
weeks without eating but
in the long run, we must
have food or we die.
What’s the first thing you
think about when you are
outside and get really cold?
Of course, you want to go
inside your house or school
to warm up. Shelter from
the weather is another one
of your needs. If it gets too
cold or too hot for people to
live, they die.
We’ve been talking about the things that
people need to stay alive, now let’s think about
the needs that animals have. Just like we do,
all animals have certain needs that must be
met if they are to survive—to live, not die.
Animals have many of the very same needs

Yes, animals get energy to move and grow
from the food they eat. Like you,
animals need food to survive.
1. The Need for Food
Animals eat plants or other animals
In addition to food, animals also need
water to survive.
2. The Need for Water
Insects get their
oxygen by breathing
through holes in their
Frogs breathe in
oxygen with lungs
and through holes
in their skin.
Although it may not be nearly as nice as
where you stay, animals also need some
type of shelter—a place where they and
their young can be safe from bad weather
and from bigger animals that may want to
4. The Need for Shelter
Some animals, such as prairie dogs, dig a
burrow underground. They do this to
escape from the heat or cold or from
other animals that are trying to eat them.
People have invented
things such as cars,
trucks and airplanes
that allow them to
move or to carry
things long distances.
Only a few people in
the world still wander
about hunting for their
food, water or shelter.
But since animals don’t drive cars, planes
or trucks, in the wild they meet their
needs in the area where they live.
Food for wild animals does not come on a
plate nor does their water show up in a
glass. Nobody builds them a home. They
have a certain amount of space to find
these things. We call the area where an
animal meets its needs area its habitat.
To mark its space or territory, an animal
like a coyote, fox or wolf urinates around
the boundary. This is like a “keep out”sign
telling other coyotes, foxes and wolves to
stay out of its space.
5. The Need for Space
For most animals finding food, water and
shelter is not easy.
Some animals need a large area or space
in which to find food, water and shelter.
Other animals need only a small amount
A male grizzly bear needs between 200 to
500 square miles to satisfy its needs for
food, shelter and water.
The city of Fort Worth takes up about
300 square miles of space.
One male grizzly bear would need an
area about the size of Fort Worth in
order to find enough food and water to
Although other animals also live in this
large area, it would take all this space
to meet the needs of one male grizzly.
On theother hand, an earthworm only
needs a very small area in which to
live—maybe a few square centimeters.
Remember the area in which an
animal lives and satisfies its needs
has a name.
This area is called its
