23.4 - Bacteria Can Be Grouped by Type of Nutrition and Response to Oxygen Flashcards
the six energy source classification for microbes
- autotrophs
- photo-autotrophes
- Chemolithoautotroph
- heterotrophs
- photoheterotrophs
- chemoheterotrophs
autotrophs (self feeders)
organisms that produce all/most of their own organic compounds from inorganic sources
the two categories of autotrophs are ____
- photoautotrophes
- chemolithautotrophes
photoautotrophes
uses light as a source of energy for the synthesis of organic compounds
chemolithoavtotrophs
uses energy obtained from chemical modifications of inorganic compounds to synthesize organic compounds
heterotrophs (other feeders)
organisms that require that require at leas one or more organic compounds from their environment
photoheterotrophs
use light energy to generate ATP, but must take in organic compounds from their environment of a source of carbon
chemoheterotrophs
organisms that must obtain organic molecules both for energy and as a carbon source
the 4 needs/responses to oxygen bacterial species differ in
- obligate aerobes
- obligate anaerobes
- aerotolerant anaerobe
- faculatative anaerobe
obligate aerobes
microorganisms that require oxygen
obligate anaerobes
microorganisms that are poisoned by oxygen
aerotolerant anaerobe
microorganisms that does not use oxygen but is not poisoned by oxygen either
faculatative anaerobe
microorganisms that can use
- oxygen in aerobic respiration
- obtain energy via anaerobic fermentation
- use inorganic chemical reactions to obtain energy
producer
an organism that synthesizes the organic compounds used by other organisms for food
decomposer
a consumer that gets its energy from the remains and waste products o other organisms
