Janwar - Animals are living things. Animals are not plants so they can't make their own food or energy by themselves. Animals have to eat other living things to get energy to live. Many animals live in this world. Some are big and some are small. Some live in water, others live on the ground and some animals can fly. Being able to move from one place to another is another distinctive characteristic of an animal.
Some animals eat only plants; they are called herbivores. Other animals eat only meat and are called carnivores. Animals that eat both plants and meat are called omnivores. Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and usually multicellular, which separates them from bacteria and most protists. They are heterotrophic,generally digesting food in an internal chamber, which separates them from plants and algae (some sponges are capable of photosynthesis and nitrogen fixation though).They are also distinguished from plants, algae, and fungi by lacking cell walls.
Animal rights, also known as animal liberation, is the idea that the most basic interests of animals should be afforded the same consideration as the similar interests of human beings. Advocates approach the issue from different philosophical positions, but agree that animals should be viewed as legal persons and members of the moral community, not property, and that they should not be used as food, clothing, research subjects, or entertainment.
