life is worth a million meanings. every person has a meaning related to it. but scientifically, the meaning of life revolves on certain points that truly differed it to a non living thing.
every living thing possesses characteristics that confirms their existence. these characteristics exists in every organism and even one has began missing, then life or the living thing will not exist.
this presentation discusses the different characteristics that a living thing possesses and how it become different from others. also, this presentation aids the reader to identify easily the different characteristics of a living thing as they analyze the different characteristics of life.

ELS - UNIFYING THEMES.pptx
1. UNIFYING THEMES
IN THE STUDY OF
LIFE
Describe how unifying themes (e.g., structure
and function, evolution, and ecosystems) in
the study of life show the connections among
living things and how they interact with each
other and with their environment. (S11/12LT-
IIa-3)
3. An organism refers to a living
thing that has an organized structure, can
react to stimuli, reproduce, grow, adapt,
and maintain homeostasis. An organism
would, therefore, be any animal, plant,
fungus, protist, bacterium, or archaeon
on earth. These organisms may be
classified in various ways.
4. Organisms in order to
survive must possess
characteristics for survival. These
characteristics are then
enumerated into different unifying
themes.
11. homeostasis
refers to the self-
regulating process by
which biological
systems tend to
maintain stability while
adjusting to conditions
that are optimal for
survival
13. Metabolism refers to
the sum of all chemical
processes that maintains
the living state of an
organism. It involves taking
in substances, breaking it
down to minute particle then
absorb by the body and use
as energy or material for
body construction. This
might be anabolism or
catabolism.
15. Growth refers to
the change that involves
physical change such as
size. Development on
the other hand refers to
the growth in function
and capability.
All organism
undergone life cycle from
juvenile to maturity.
17. Stimulus refers to a
thing that evokes a
specific functional
reaction in an organ or
tissue.
Every organisms
and organs has specific
reflex on each stimulus.
Failure to response
immediately to a stimulus
19. Reproduction refers to
the production of offspring –
either sexual or asexual.
Reproduction involves the
passing of genes from
parents to offspring.
Reproduction is a
fundamental feature of all
known life; each individual
organism exist as the result
of reproduction.
21. Evolution refers to
the change in the physical
and heritable traits of
organisms over successive
generations. Organisms
change over time to adapt
to their environment to
survive. Extinction on the
other hand happens when
organism fail to adapt and
evolve from that
23. No man is an
island. All organisms
need to interact with
each other to prosper
and survive. These
interactions later on
develops to
relationships and further
develop defined
characteristics that
24. Group of organisms forms
population and later on collectively
turns into community then to
biodiversity and lastly, a group of
biodiversity as it interacted with will
then form into Ecosystem. A study
of Ecosystem is termed ECOLOGY.
25. ECOLOGY is the branch of biology that deals
with the study of living organisms and their
relationships with each other and their environment

Editor's Notes
1. from the DNA, it contains the program in producing structures starting with cells. Group of cells will make an organ, an organ will interconnect with other organ to form organ system and an group of organ system will comprise the whole individual
Relationship exists between structure and function at all levels of biological organization. In biology, structure is always related to function. Hence, the hierarchy of structural levels is the basis for the biology organization. Structural levels are built on the levels that precede it. Within the many kinds of organisms in the living world, body structures seem to be carefully designed to carry out their functions. For example, hummingbird sucks nectar from a deep flower through its long tongue.
1. organisms develop characteristics in order for them to adjust in any environment or situation they are thriving.
Penguins, though not capable of flying and mostly thrive on polar environments have develop extra layer of skin made up of fats in order for them to survive extreme cold temperatures.
If homeostasis is successful, life continues, if not, disaster or death ensues.
Example, if an organism cannot balance the temperature of their body they might die or suffered from hypo or hyperthermia
Catabolism – breaking down
Anabolism – building up
Energy is used by organisms to grow and do work. Without it life stops. Almost all the energy that living things need is obtained from the sun. Plants capture the energy from sunlight and use it to make complex molecules in a process called photosynthesis. These molecules then serve as the source of fuel for animals that eat them. The flow of energy among organisms helps determine how organisms interact within their environment
