* Sunlight: Trees capture sunlight using chlorophyll, a green pigment found in their leaves.

* Carbon Dioxide: Trees absorb carbon dioxide from the air through tiny openings called stomata on their leaves.

* Water: Trees absorb water from the ground through their roots.

* Sugar and Oxygen: Using sunlight, carbon dioxide, and water, trees create sugar (glucose) for energy and release oxygen as a byproduct.

This process happens during daylight hours when the sun is providing energy.
