Everything on Earth is either living or nonliving. A living thing is alive. A nonliving thing is not alive.
Both animals and plants are living things. Rocks, air, and water are nonliving things. There are many kinds of animals and plants. But they are similar in some ways. All of them need oxygen to survive. They also need food and water. When they eat and drink, they get nutrients. Nutrients provide energy for them. Most plants and animals need sunlight, too. Living things can also make new living things like themselves.
Nonliving things are not alive. They cannot move. They cannot breathe. They cannot make new things like themselves.
