How Bacteria Effects Our How Bacteria Effects Our LivesLives Positive: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: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 How Viruses Effect Our LivesLives Positive: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: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 How Protists Effect Our LivesLives PositivePositive 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 one-half 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..

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.
