1. Sunlight: Trees absorb sunlight through their leaves.
2. Carbon Dioxide: Leaves take in carbon dioxide (CO2) from the air through tiny pores called stomata.
3. Water: Water is absorbed from the soil through the roots and transported to the leaves.
4. Chlorophyll: Inside the leaves, green pigment called chlorophyll helps capture the sunlight's energy.
5. Sugar & Oxygen: Using sunlight energy, the leaves combine CO2 and water to produce sugar (glucose) for the tree's energy and oxygen (O2) as a byproduct.
6. Oxygen Released: The leaves release the oxygen back into the atmosphere through the stomata.
In essence, trees use sunlight to transform carbon dioxide and water into their food (sugar) and release oxygen as a waste product. This oxygen is essential for all living things, including humans, to breathe and survive.
Here's a simple analogy: Imagine a tree is like a tiny factory. It takes in raw materials (CO2 and water), uses sunlight as energy, and produces food (sugar) and a waste product (oxygen). This oxygen is then released into the air for us to breathe.
