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.
All bacteria are one-celled organisms. Their cells are consid-ered to be prokaryotic (proh kar ee AH tihk) because they do not have their genetic material in a nucleus. Some bacteria are found as individual cells.Others grow in groups or in long chains of cells. Producers and ConsumersBacteria obtain their food in a variety of ways. Some bacteria use energy from sunlight to make their own food. Other bacteria use energy from inorganic chemicals to make food. Any organism that can make its own food is called a producer. Organisms that canât make their own food are called consumers. Consumer bacteria obtain food in many ways. Some
