They are not, there just used for eating and producing food for us.
The flesh eating animals are carnivores, the plant eating animals are called herbivores. Carnivores depend on the nutrients in meat and flesh, while the herbivores depend on the nutrients in plants. The carnivores have teeth that were made for tearing and ripping flesh, while herbivores have teeth that were made for crushing plants.
Habbit means something you are addicted to doing
flesh eating carnivore animals are generally sharper as they rip off flesh of a animal and the plant eating animals herbivores teeth are blunter as they just eat plants their teeth are also flat so they can grind the food before swallowing
Different animals show different ways of getting/eating their food.
Eating Animals was created in 2009.
A natural habbit is something you do alot mostly without thinking.
