Plants need sunlight to grow and stay healthy. They use a special process called photosynthesis to make their own food. During this process, plants take in carbon dioxide from the air and water from the soil. They turn these ingredients into sugar to provide energy for themselves. While making food, plants also release oxygen, which is essential for humans to breathe. Therefore, plants are very important for life on Earth.
