Where do Heterotroph's get their cardbon?
From organic compounds in nature
Where do Autotrophe's get their cardon?
From CO2 in the atmosphere
How much help do Fastidious Heterotroph's need?
- Need a lot of help
- Rely heavily on the environment to supply organic compounds
How much help do Nonfastidious Heterotroph's need?
- Need a few simple organic compounds
- They can do the the rest by themselves
Amount and identity of every ingredient is known
contains plant/animal extracts; rich in nutrients
Example; beef extract
grows in the presence of oxygen
does not grow in the presence of oxygen
requires o2 to grow. Uses O2 as final electron acceptor in aerobic respiration
survives/grows DESPITE presence of O2 is present; uses anaerobic respiration if it is not
requires O2 to survive (aerobic respiration), but needs lower concentrations than normal atmospheric concentrations
thrives in presence of high levels of CO2
