How do viruses, bacteria, and
protists effect our lives in both
positive and negative ways?

How Bacteria Effects Our Lives






Positive:
Archaebacteria produce
Methane (a major component
in about 20% of earths
deposits of natural gas)
Heterotrophic eubacteria are
decomposers and break down
large chemicals in dead
organisms into small
chemicals
Some bacteria help make
medicines
Some help digest food
Some make vitamins your
body needs



Negative:
Some bacteria cause food to
spoil when they break down
the chemicals
Some cause
diseases/illnesses, which can
be mild (like strep throat) or
life threatening (like
Tuberculosis )
How Viruses Effect Our Lives


Positive:
Scientists take advantage of
the fact that viruses are
cells so they use them as
messengers by and good at
getting inside taking out the
bad genetic material of a
virus and put in information
that the virus will later
deliver to cells that don't
work properly. The
information the virus gives
the cell helps it do its job
right.



Negative:
Viruses can cause harm to
any living thing, not one of
the six kingdoms is
completely safe from them
Many viruses cause life
threatening diseases
How Protists Effect Our Lives






Positive
Some clean intestines out.
Some protists break cellulose
down into carbohydrates.
protists form a broad base
across the bottom of the
food chain
supply approximately onehalf of the world’s oxygen
(unicellular algae compose a
large portion of the world’s
phytoplankton).
Protists, along with bacteria
and fungi, are responsible
for decomposing and
recycling nutrients..


Negative
Many are parasitic. Some
examples are: Plasmodium,
a protist that cause malaria,
Trypanosoma, a protist that
cause African sleeping
sickness, and dinoflagellate
that cause the red tide.
