What three groups can be animals divided into based on how they get energy?

- Autotrophs (also called producers) make their own food through photosynthesis or chemosynthesis. (Examples include plants, algae, and some bacteria)

- Heterotrophs (also called consumers) get their energy by consuming other organisms. (Examples include animals, fungi, and most bacteria.)

- Mixotrophs can both produce their food and consume other organisms for energy. (Examples include some species of protist.)
