The forest canopy is the upper layer of a forest, formed by the tops of trees. It plays a crucial role in the ecosystem, providing habitat for many species, including birds, insects, and mammals. The canopy also helps regulate temperature and humidity, creating a unique environment for various plants and animals. Light filtering through the canopy supports photosynthesis in the understory plants below. This layer is vital for maintaining biodiversity and contributes to the overall health of the forest. The canopy can vary in height and density depending on the type of forest, such as tropical rainforests or temperate forests.
