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.
Different kinds of protists get their food in different ways.  Some protists can move and can take in food like animals do.  Plant-like protists need to absorb the sun's ene â¦ rgy in order to  make food inside their bodies. Other protists like fungus grow  above their food source to get nutrients.Some protists engulf  bacteria and digest them internally, by extending their cell  membrane and forming a vacuole around the bacteria.ther protists like fungus grow  above their food source to get nutrients.
