Living things such as people, animals and plants are born, grow, reproduce and die. Vertebrates have backbones and include animals such as fish, bears and tortoises while invertebrates like frogs do not have backbones. Domestic animals live with people on farms or in homes and people care for them, while wild animals live independently in nature. Animals have protective coverings like fur, feathers, scales or shells and eat plants as herbivores, other animals as carnivores or both as omnivores. They also reproduce by being born live from their mothers as viviparous or hatching from eggs as oviparous.
