It includes all
living organismson earth,
together with the
dead organic
matter produced
by them.
It is the biologicalcomponent of
earth systems,
which also include
the lithosphere,
hydrosphere,atmosphere and
other "spheres“.

a forest of trees
and undergrowth
plants, inhabitedby animals and
rooted in soil

It is an interactinggroup of various
species in a

They are capable
of some degree

reproduction,
growth and

It is a group of
tissues in a living
organism thathave been
adapted to
perform a
specific function.
In higher animals,
organs are
grouped into
organ systems.
The Organ

It is is an
ensemble of
similar cells fromthe same
origin that
together carry
out a specific
function.
The study of tissue
is known
as histology.

It is the basic
structural,functional, and
biological unit of
all known living
organisms.
A cell is the
smallest unit of
life that
can replicate
independently,
and cells are often
called the
"building blocks
of life".
The Cell

It is a specialized
subunit withina cell that has a
specific function.
Individual
organelles are
usually separately
enclosed within
their own lipid
bilayers.

It is an
electrically
neutral group of
two or more
atoms held
together by
chemical bonds.
Molecules as
components of
matter are
common in
organic substances
(and therefore
biochemistry).
The Molecule

It is the smallest
constituent unit
of ordinary
matter that has
the properties of
a chemical
element.
Atoms are very
small; typical sizes
are around
100 pm (a ten-
billionth of a
meter, in the short
scale).
The Atom

They are particles
much smaller
than atoms.
There are two
types of
subatomic
particles: element
ary particles,
which according to
current theories
are not made of
other particles;
and composite
particles.
