How do oak trees exhibit use of energy?

Oak trees exhibit energy use primarily through photosynthesis, where they convert sunlight, carbon dioxide, and water into glucose and oxygen. This glucose serves as energy for growth, development, and reproduction. Additionally, oak trees store energy in the form of carbohydrates in their roots and wood, which they can draw upon during periods of dormancy or stress. Through these processes, oak trees play a crucial role in energy dynamics within their ecosystems.
