How Trees Make Food for Themselves
Leaves are the food processing factories for trees. The plants use their roots to take in water and other essential nutrients. The leaves then use the water and carbon dioxide from the air, in combination with sunlight, to turn the water and carbon dioxide into glucose, also giving off the byproduct oxygen in the process. It then uses the glucose for energy for growing and maintaining itself. Excess glucose is turned into starch and used during winter for food.
