Classification
in
Biology
We
can
classify
all
the
things
in
the
world
into
two
big
groups
:
living
things
and
non
-
living
things
.
We
call
living
things
biotic
factors
and
non
-
living
things
are
called
abiotic
factors
.
things
have
common
characteristics
as
they
can
move
,
breathe
,
grow
and
have
young
ones
.
They
also
need
food
.
things
are
different
because
they
do
not
have
these
.
Monkeys
,
trees
,
and
flowers
are
examples
of
things
but
glass
,
water
,
,
metal
and
oxygen
are
things
.
We
can
subdivide
into
two
more
groups
:
animals
and
plants
.
Why
do
we
do
this
?
The
answer
is
because
they
are
in
many
ways
.
Plants
move
from
place
to
place
.
They
have
not
got
brains
,
,
lungs
or
blood
,
but
they
are
.
Also
,
plants
can
do
something
very
important
which
animals
cannot
.
Plants
can
make
their
own
food
.
Grass
,
wheat
,
roses
and
gum
-
trees
are
all
types
of
plants
.
However
,
not
all
plants
have
on
them
so
we
can
divide
them
into
two
groups
:
flowering
and
-
flowering
plants
.
Roses
,
daffodils
and
fruit
trees
all
have
flowers
,
but
mushrooms
,
fungi
and
ferns
do
not
.
We
can
also
animals
into
two
groups
:
vertebrates
and
invertebrates
.
such
as
dogs
,
people
,
birds
and
frogs
have
a
,
whereas
jelly
-
fish
,
butterflies
and
spiders
do
not
.
There
are
five
important
groups
of
vertebrates
:
mammals
,
birds
,
reptiles
,
amphibians
and
fishes
.
So
you
can
see
that
we
put
some
things
together
in
a
group
because
they
are
similar
in
many
ways
and
they
have
characteristics
which
divide
or
separate
them
from
other
things
.
In
other
words
,
we
classify
things
.
We
make
so
that
it
is
easier
to
learn
about
things
.
