Biological organization
Based in a
hierarchy
of
structural levels

Atom
The
lowest
level that are ordered into
complex biological molecules
Organelles
Many
molecules
that are arrange into
minute structure
and which are the
components
of
cells
Cells
The
subunits
of
organisms
, the
units
of
life
Multicellular
Exhibiting
three
major
structural
levels above the cell;
tissue
,
organ
,
organ system.
Population
Localized
groups of
organisms
belonging to the same
species
Community
Population
of
several species
in the
same area
Metabolism
The process of getting
energy
from nutrient molecules of food and using it to
maintain
the structure and
function
of a cell
Anabolism
Is called the
structure
or
building up phase
Anabolism
Building up
protoplasm
from
simple compounds
and
elements
which are
product
of
digestion
Catabolism
The
destructive
or
breaking down
phase
Ecosystem
The population
interacts
with their physical
environment
Homeostasis
The
maintenance
of a
stable
level of
internal conditions
Reproduction
Living things become
capab
of
perpetuating
their own kind
Reproduction
It can be
asexual
or
sexual
Asexual
Only a
single
parent is needed
Sexual
Requires
two
parents; involves
gametes
or
sex cell
The ability of
living
things to respond often results in
movement
Adaptation
Special characteristics
that enable
plants
and
animals
to be successful in a particular
environment
Adaptation
Afford the organisms a
better
chance to
survive
Problem
Identifying or defining a problem
Hypothesis
Accumulating
data and formulating
tentative
hypothesis
Experiment
Testing hypothesis
Conclusion
The
outcome
result of the tested data
