Well Carnivores is an obvious answer, but have we looked in the mirror lately? If you're a vegetarian then you can ignore me. We eat other organisms by meat like cows, hens, and even pigs! We are definitely apart of that. Mammals basically. Amphibians could eat bugs. Reptiles eat meat.
bacteria can live in hotter and colder temperatures than humans but they do best in a warm moist protein-rich environment that is pH neutral or slightly acidic
