Four nutritional classifications of bacteria?

Back 1

1. Autotrophs
2. Heterotrophs
3. Phototrophs
4. Chemotrophs

Front 2

Autotrophs

Back 2

• Bacteria that can take inorganic substances into their bodies and transform them into organic nourishment
• Use CO2 as principal carbon source

Front 3

Heterotrophs

Back 3

• Bacteria that require an organic carbon source for nutrients
• Cannot form their own food

Front 4

Phototrophs

Back 4

• Use light for the synthesis of energy
• Synthesize energy using photosynthesis

Front 5

Chemotrophs

Back 5

• Bacteria which obtain chemical energy from their surroundings and convert it into adenosine triphosphate (ATP) for cellular use
• Uses oxidation reduction reactions as primary energy source
