How does sunflowers use energy?

Sunflowers use energy primarily through photosynthesis, a process where they convert sunlight into chemical energy. They absorb sunlight using their leaves, which contain chlorophyll, and transform carbon dioxide from the air and water from the soil into glucose and oxygen. The glucose serves as energy for growth, reproduction, and other metabolic processes, while the oxygen is released into the atmosphere. Additionally, sunflowers exhibit heliotropism, where young buds track the sun's movement to maximize light absorption throughout the day.
