A canopy is a covering that provides shelter or shade, often made from fabric, wood, or metal. Canopies are commonly used in outdoor settings, such as gardens, parks, and events, to protect people from sun and rain. They can be freestanding structures or attached to buildings, like patios or decks. In nature, a canopy refers to the upper layer of trees in a forest, which forms a dense cover over the ground. This layer is crucial for many ecosystems, as it provides habitat for various species, including birds and insects, and plays a role in regulating temperature and moisture levels in the forest.
