A: Bacteria obtain energy by either ingesting other organisms and organic compounds or by producing their own food. The bacteria that produce their own food are called autotrophs. Bacteria that must consume other organic molecules for energy are called heterotrophs.
Bacteria have three ways of transferring bacteria between cells: 1  Transformation: The uptake and incorporation of external DNA into the cell thereby resulting in the alteration of the genome. 2  Conjugation: The exchange of genetic material through cell-to-cell contact of two bacterial cells.
