A canopy or forest canopy is part of a tree, forest, group of trees, or group of other tall plants. It is where the leaves spread out like a roof or umbrella.[1]
The canopy is where the most sunlight touches the plants, so it is where the most energy enters living things.[2] It is also where the most gas exchange happens, where oxygen and carbon dioxide and water vapor go in and out of the leaves.[3] Many animals live in the canopy.
