What is the role of cellular respiration and photosynthesis to support your answer from the previous question?

Cellular respiration and photosynthesis are fundamental biological processes that sustain life on Earth. Photosynthesis converts sunlight into chemical energy, producing glucose and oxygen, which are essential for plant growth and energy storage. Cellular respiration then takes this glucose and oxygen to generate ATP, the energy currency of cells, while releasing carbon dioxide and water. Together, these processes create a cycle of energy flow and matter recycling, supporting ecosystems and maintaining atmospheric balance.
