BACTERIA HABITATS

FILL IN THIS TABLE WITH INFO FROM THE FOLLOWING 3 SLIDES

Bacteria Type Description Example/Info

Aerobic

Anaerobic

Facultative Aerobe

Aerobic – thrive in the presence of oxygen and need it for their continued growth and existence

Obligate aerobes – require oxygen for survival

http://www.textbookofbacteriology.net/tuberculosis.html

Anaerobic – cannot tolerate gaseous oxygen, such as those bacteria which live in deep underwater sediments, or those which cause bacterial food poisoning

Obligate anaerobes – cannot live in the presence of oxygen

http://www2.cedarcrest.edu/academic/bio/hale/bioT_EID/lectures/tetanus-pathogen.html

Facultative anaerobes - prefer growing in the presence of oxygen, but can continue to grow without it.

BACTERIA NUTRITIONAL PREFIXES

Hetero = Other

Auto = Self

Photo = Light

Chemo = Chemical

Troph = Nourishment

Bacteria have 2 main nutritional needs, a source of carbon to build molecules and a source of energy in order to function

HETEROTROPH – OBTAINS CARBON FROM OTHER ORGANISMS

Photoheterotroph – uses light energy but gets carbon from other organism

http://www.biology-online.org/dictionary/Photoheterotroph

Chemoheterotroph – obtains energy chemically and gets carbon from other organism

http://www.biology-online.org/dictionary/Chemoheterotroph

AUTOTROPH – OBTAINS CARBON DIRECTLY FROM CO2 (CARBON DIOXIDE)

Photoautotoph – uses light as energy source and gets carbon from CO2, like a plant

Chemoautotroph – uses chemicals as energy source and gets carbon from CO2 (methanogens)
