Archaea & Bacteria
Cell Type: Prokaryote (no nucleus)
How it Gets Food: Autotrophic & Heterotrophic
Cell Number: Unicellular (single-celled)

Where do you find bacteria?
Archaea Dense mud of swamps and marshes In the guts of animals and termites Very salty lakes and ponds Extremely hot and cold places
Bacteria Everywhere

Bacteria can be helpful or harmful
Helpful Breaks down dead and
decaying organisms Breaks down sewage Change material that do
not come from living things and make them available for other organisms.
Clean up oil spills
Harmful Causes disease

Bacterial Roles
Producer: Bacteria that transforms energy from the sun into energy that can be used by cells.
Decomposer: Bacteria that gets its energy by breaking down materials in dead or decaying organisms.
Parasites: Bacteria that harms its host.
