Where does a producer such as a tree get the energy it needs to survive from the air?

A tree, as a producer, gets the energy it needs to survive primarily through the process of photosynthesis. It absorbs carbon dioxide from the air through tiny openings in its leaves called stomata. Using sunlight as an energy source, the tree converts this carbon dioxide and water from the soil into glucose and oxygen. The glucose serves as energy for growth and metabolism, while the oxygen is released back into the atmosphere.
