Our lives depend on leaves because leaves produce two
essentials: (1) food and (2) oxygen. Leaves are part of the
food chain which effects our lives everyday. Everything we
eat is somehow linked to leaves.
Leaves photosynthesize producing energy for itself.
However, when an animal eats that plant, it stores the
energy that it obtained from the plant. When we humans eat
that animal, we get the energy that it obtained from the
plant AND in the animal.
Carbon dioxide is taken in by the leaves and oxygen is
given off. We breathe the oxygen that the plant had given
off and we supply it with more carbon dioxide.
So as you can see, leaves are vital and very important to
staying alive and healthy. Leaves are important to all
living beings, not just humans.
