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 come in three main shapes: 1) Spherical (like a ball). These are usually the simplest ones. Bacteria shaped like this are called cocci (singular coccus). 2) Rod shaped. These are known as bacilli (singular bacillus). Some of the rod-shaped bacteria are curved; these are known as vibrio.
