Oxygen is released as a waste product by plants during the process of photosynthesis. Animals takes in this oxygen and releases it as carbon dioxide during the process of respiration. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
Photosynthesis produces oxygen and glucose from carbon dioxide and sunlight, while respiration breaks down glucose using oxygen to release energy, carbon dioxide, and water. Together, these processes create a cycle essential for the survival of plants and animals. This natural cycle regulates atmospheric gases, supporting life on Earth.
