what living beings do

All living things can move, using their own energy. Even though plants stay in one spot, they move their leaves to get sunlight. Living things are also sensitive, or able to feel. The simplest life-forms can feel only when they are touched, or they have only a sense of hot and cold.

Living things take in and release certain chemicals. Animals breathe in oxygen and breathe out carbon dioxide. Green plants take in carbon dioxide through their leaves and release oxygen. All organisms need the nutrients and energy that food gives. Green plants make their own food with the help of sunlight. Animals eat plants and other animals to get energy. Organisms also release waste. After they take in nutrients, they get rid of the part that is not needed.

Living things grow. When many cells in a plant or an animal divide, the plant or animal becomes larger. Making new parts is another kind of growth. Organisms also reproduce, or create new life. Animals have babies. Plants make seeds or spores that grow into new plants.
