Animals can live in all sorts of
different areas, from deserts to
rainforests.
Most animals have a particular
set of conditions which they like
to live in.
Adapted for life
A place with this set
of conditions is
called their habitat.
You can think of it as
an animal’s home.

Adapted for life
After a species of animal
has lived in a habitat with
a specific set of conditions
for millions of years, it’s
body can begin to change,
making it easier to survive
there.
These changes are called
adaptations.
Adapted for life
Animals can adapt in different
ways.
Sometimes an adaptation will
help them to find food.
On other occasions it will allow
them to live in extremely hot or
cold conditions.

Look at the pictures of
these animals from the
Amazon rainforest and
try to identify what their
adaptation is and how it
helps them…

Tapir
The tapir has developed a
long flexible nose which it
uses to rummage on the
ground for food.

Toucan
Many of the nuts and fruits in
the Amazon have developed
a tough outer layer to help
protect them from being
eaten.
This doesn’t work with a
toucan though as they have
developed a huge tough beak
which they can use for
cracking most nuts.

Giant anteater
The giant anteater
has developed a long
sticky tongue which it
uses for extracting
ants from their nests.

Jaguar
The jaguar has developed
the perfect disguise for
the dappled light which
falls on the forest floor –
it’s beautiful spotted coat!
Adapted for life
Spider monkey
The spider monkey lives at the
top of tall trees in the Amazon,
almost never coming to the
ground.
It has developed an incredibly
strong and flexible tail which it
can use as an extra arm to
hang from when collecting fruit.

Food chains
All living things (plants and
animals) need energy to
survive.
Plants normally get their
energy through capturing the
sun’s energy (photosynthesis).
Animals either need to eat
plants (e.g. leaves or fruit) or
other animals in order to create
energy.
Food chains
Food chains can be used to show what eats what.
For example….
Leaves
Ants
A food chain must always start with a plant as they
catch their energy from the sun.
Food chains
A food chain can only travel in one direction. This
direction is shown using an arrow.
E.g. the monkey eats the fruit, the ocelot eats the
monkey.

The water cycle
The water cycle is
the name for the
journey which water
takes from the sky to
the earth and back
again.
The water cycle
It relies on three really important processes:
Evaporation: This is when water heats up and turns
from a liquid to a gas.
Condensation: The opposite of evaporation, when
water turns from a gas to a liquid.
Precipitation: This is water that falls from the sky. It
could be in the form of rain, snow, sleet or hail.
The water cycle
The water cycle is really
important because it keeps
bringing fresh water to the
land.
Look at the diagram on
your worksheet and see if
you can attach the correct
label to each part of the
water cycle to show how it
works.
The carbon cycle
All living things are made from carbon. This includes
animals, trees and flowers!
Carbon is even part of the air we breathe. When it is
attached to oxygen it is called carbon dioxide.
Plants use carbon dioxide and sunlight to grow. They
absorb the carbon dioxide and turn it into carbon which
they store.
The carbon cycle
When plants die and decompose the carbon they had
stored inside them goes back into the earth.
This can then be absorbed by other plants who use it to
grow.
It can also turn into fossil fuels although this can take
millions of years.
The carbon cycle
When we burn fossil
fuels or trees the carbon
that they had stored
inside them goes back
into the atmosphere as
carbon dioxide.
This can all be shown as
the carbon cycle.

Why do you think
the Amazon is so
important in the
carbon cycle?

The carbon cycle
If we burn down lots of trees and fossil fuels then
more carbon dioxide will go into the atmosphere.
If we have destroyed lots of trees then there will also
be fewer available to absorb the carbon dioxide so
some will stay in the atmosphere.
Carbon dioxide in the atmosphere is one of the main
contributors to climate change.
