Lab practical study - Carbon source, Energy source, Electron source

Heterotroph

Gets carbon from organic compounds (like glucose)

Autotroph

Uses CO₂ (inorganic carbon) to make its own molecules

Mixotroph

Can use both organic AND inorganic carbon

Phototroph

Gets energy from light

Chemotroph

Gets energy from chemical compounds

Organotroph

Uses organic molecules as electron donors

Lithotroph

Uses inorganic molecules (like NH₃, Fe²⁺)
