- Heterotrophic Organisms - gain their high energy food from other organisms
- Herbivores - eat plants
- Ruminants - large stomachs with symbiotic bacteria that digest cellulose
- Can feed almost anywhere

- Ruminants - large stomachs with symbiotic bacteria that digest cellulose
- Carnivores - eat other animals
