A tree is a tall plant with a trunk that supports branches and leaves. Trees come in many shapes and sizes, and they can be found in forests, parks, and even in our backyards. They play a vital role in our environment by providing oxygen, improving air quality, and offering habitats for various animals. Trees also have many uses for humans. We use wood from trees to build houses and furniture, while fruits and nuts from trees provide food. Additionally, trees offer shade on hot days and enhance the beauty of our surroundings, making them an essential part of nature and our lives.
