The job of the umbrella of leaves, or crown , of each canopy tree is to grab as much sunlight as it possibly can. The leaves of each tree also have another important job to perform.
Photosynthesis occurs in the leaves.
This is a process in which sunlight, water, and carbon dioxide are converted, or changed, into food for the plant. The trunk of a canopy tree is a transport , or travel, system. Food is transported from the leaves throughout the tree so that it can be properly nourished , or fed. We have veins in our bodies, too. Blood is transported through our veins.
