Plants need sunlight to grow and stay healthy. They use energy from the sun to make their own food through a special process. During this process, plants take in carbon dioxide from the air and release oxygen. This cycle is essential because it provides the air that humans and animals breathe. Without plants, life on Earth would be very difficult. Therefore, we should protect plants and the nature around us.
