Photosythesis
It is because of the presence of chlorophyll in the leaves which enable the trees to make sugar to use as fuel to stay alive.
Olive leaves are great for medical use. It was first used medicinally in Egypt. Medicine made with olive leaves are to stabilize blood sugar and control diabetes.
The trees use a process called photosynthesis to produce food for themselves - they take in sunlight, carbon dioxide and water to make sugar and oxygen. They use the sugar as food, but they don't need a lot of oxygen so the excess oxygen leaves the trees through the stomata (holes) in their leaves, and enters the air. Humans breathe oxygen, so the trees help us to breathe by providing us with plenty of oxygen.
they use their necks to get leaves from trees
Giraffes are herbivores. Planteaters usually eat leaves from trees. But they don't eat leaves from pine trees or oak trees. They use their long necks to reach up to trees to pluck the leaves off and eat them.
So-called "vascular" plants (such as vegetables, flowering plants, and trees) have a system of cell channels known as "phloem cells" that carry sugar from the production areas (mostly leaves) to storage areas or to cells that use the sugar.
Sugar is Sugar. But some sugars like Splenda has aspartame in it .Aspartame cause cancer if you use it to much so the sugar I recommend Truvia. This is a natural sugar made from leaves.
Trees,birds[food], leaves

To use to get to leaves high in the trees.
The leaves of trees take carbon dioxide and water and make sugar. Trees take sugar molecules and combine them to make starch. They take starch molecules and make even bigger molecules. They paste those molecules together. Tall trees consist of many molecules of different sizes pasted together. Factories remove part of the glue in wood in trees and turn trees into long chain molecules. They can take these long chain molecules and lay them flat and thin and they produce paper.
leaves are what trees use to breathe when the tree has too many it takes some off a tree balances its leaves
