2. • An
ecosystem
in
a
community
of
plants
and
animals
living,
interac=ng,
and
feeding
in
the
same
environment.
• The
living
things
of
an
ecosystem
rely
on
the
non-‐living
things,
such
as
weather,
sun,
water,
and
soil,
to
help
them
thrive.
• Without
all
of
these
parts
the
ecosystem
would
not
be
able
to
survive.
They
rely
upon
each
other.

is
an
Ecosystem?
3. Facts
about
the
Forest
• The
forest
ecosystem
is
usually
a
wet
or
moist
place.
There
can
be
lots
of
rainfall
which
leads
to
a
very
humid
climate.
• The
temperature
of
the
forest
ecosystem
varies
on
where
the
forest
is.
If
it
is
a
rain
forest
the
temperature
will
be
warm
most
of
the
year.
Other
forests
will
have
temperatures
that
will
vary
depending
upon
the
season.
• The
animals
and
plant
life
that
live
in
the
forest
require
the
climate
that
is
part
of
the
forest
ecosystem.
They
need
the
moist
climate
to
live.
Some
animals
might
include
frogs,
birds,
insects,
and
mammals.
4. Facts
about
the
Desert
• The
desert
is
a
very
dry
ecosystem
geIng
very
liJle,
if
any,
rainfall
in
a
year.
• Plants
and
animals
that
survive
in
the
desert
have
special
adapta=ons
that
allow
them
to
live
in
the
harsh
climate.
Some
of
these
adapta=ons
are:
big
ears
for
cooling
off,
storing
water
in
their
bodies
to
use
at
other
=mes,
burrowing
into
the
ground
to
stay
out
of
the
hot
sun,
and
by
laying
dormant
un=l
the
rain
comes.
• Some
of
the
plants
and
animals
that
enjoy
this
ecosystem
are
the
camel,
elephant,
jack
rabbit,
and
the
cactus.
5. Facts
about
the
Tundra
• The
tundra
can
be
referred
to
as
a
cold
desert
• The
tundra
ecosystem
is
only
has
two
season,
winter
and
summer.
In
the
winter,
the
tundra
can
get
as
cold
as
-‐18°
F.
In
the
summer,
it
can
get
as
warm
as
54°
F.
• In
the
winter,
the
night
can
last
for
days
and
weeks
because
of
the
posi=on
of
the
sun.
• Some
of
the
animal
and
plant
adapta=ons
of
tundra
dwellers
can
be
thick
fur,
blubber,
and
low
metabolism.
• Some
animals
include
the
polar
bear,
snowy
owl,
caribou,
and
the
ar=c
fox.
6. Facts
about
the
Ocean
• The
ocean
makes
up

half
of
the
earth’s
surface.
• The
climate
in
the
ocean
can
vary
depending
on
where
you
are.
The
closer
to
the
surface
the
warmer
the
water
is
and
the
deeper
you
go
down
the
colder
it
becomes.
• Animals
and
plants
have
learned
to
adapt
to
the
condi=ons
of
the
ocean.
Some
animals
and
plants
live
so
far
down
in
the
ocean
that
there
is
no
light,
the
water
is
frigid,
and
the
pressure
is
tremendous.
Some
animals
will
migrate
and
follow
their
food
source
from
colder
waters
to
warmer
waters.
• Some
animals
in
the
ocean
ecosystem
are
whales,
sharks,
many
kinds
of
fish,
shrimp,
and
sponges.
7. • What
would
happen
without
ecosystems?
• Would
the
world
be
the
same
if
the
ecosystems
were
different?
• Do
you
think
things
would
change
if
one
of
the
ecosystems
were
gone?
• Could
animals
and
plants
in
one
ecosystem
be
able
to
survive
in
another?
• Are
humans
hur?ng
the
world’s
ecosystems?
If
so,
why?
If
not,
why
do
you
think
that?
• Could
we,
as
humans,
be
doing
more
to
help
the
ecosystems?
