A canopy is a covering that provides shelter or shade, often found in forests where the upper layer of trees forms a dense layer of leaves. This layer is crucial for many ecosystems, as it helps regulate temperature and humidity, while also providing habitat for various species, including birds and insects. In urban settings, canopies can refer to structures like awnings or pergolas that offer shade and protection from the elements. They are commonly used in parks, gardens, and outdoor dining areas to enhance comfort and aesthetics while allowing people to enjoy the outdoors.
