- BIOTIC AND ABIOTIC FACTORS
- Fun Fact: Most of the people
including me may think that DNA is
alive, but what is the reality?
Actually the answer is that DNA is
not a living thing, but it is a
essential part of living things cause
without its pretense life would not
exist. Why? It cannot maintain
homeostasis, its doesn't grows, it
never dies and it is a molecule.
- How can you know if it is abiotic or biotic?
Well biotics....
- 1. Metabolism
- 2. Components
cells, the basic
until of life
- 3.Develops and grows
- 4. Responds to stimuli
- 5. Reproduction
- 6. Adapts and change
- 7. Maintins homeostasis
- Exapmles
- Abiotic:
Mountain, Clouds,
River, Virus, Rock,
Sunlight
- Biotic: Humans, Mold,
Producers, Consumers,
Decomposers,
- MATTER
- PROPERTIES
- Physical Properties
- Intensive: do not depend on
the amount: color, taste,
melting point, boiling point,
density, luster and hardness
- Extensive: Depend on the
amount: mass, volume,
length and shape
- Chemical Properties
- How does the
substances react
in the presence of:
air, an acid, water,
bases, other
chemicals
- CONCEPT
- Anything that takes up space and
splays the properties of mass and
inertia
- Levels of Matter
- Atom, molecule, cell,
tissue, organ, body
system, organism,
population, community
and finally ecosystem
- CLARIFICATION
- There are two
parts
- Composition:
Components of a
sample and their
relative properties
- Properties:
Distinguishing qualities
or attributes of a sample
of matter
- STATES
- Bose-Einstein
Condensate: A dilute
gas of bosons cooled
to temperatures very
close to absolute zero
- Solid: less energetic state, holds shape and fixed volume it
can hard, force, have elasticity, confession and vibrate.
- Liquid: between solids and gases,
shape of container, free surface,
fixed volume, can have viscosity
- Gases: more energy, low concession
force and diffusion, shape of
container and also its volume
- Plasma: is
abundant in
the universe, it
has equal
number of
protons and
electrons,
super hot
- can it be separated?
- Yes! They are mixtures
- Is the composition uniform?
- if the answer is yes,
it is homogeneous
this means you
cannot identify its
components (air,
sugar in water,
stainless steel)
- If the answer
is no, it is
heterogeneous
like granite,
wood)
- No! Pure substances
- can it be decomposed by ordinary chemical means?
- If it can they are
compounds like water,
sodium, chloride,
sucrose, etc.
- If it cannot they are
elements, the ones
on the periodic
table
- CONCEPT (from the
Environmental Chemistry
TextBook)
- Matter is the physical material that forms building, block of
both biotic and abiotic components while energy provides
the force to hold the structures or building blocks together
or make some changes or move them from one place to
another.
- Every matter consists of
tiny particles called
atoms.
- We can find the
conservation of matter this
consists of the theory that
under ordinary
atmospheric conditions no
matter can be created or
destroyed but it is recycled
again and again through
different processes called
biogeochemical cycles.
