A water lily in a pond often releases visible bubbles underwater—evidence of oxygen being produced during photosynthesis! In this process, aquatic plants convert sunlight, carbon dioxide, and water into glucose and oxygen. According to research from the Woods Hole Oceanographic Institution, ocean-based photosynthetic organisms like phytoplankton generate over half of the Earth’s oxygen, underscoring the essential role of aquatic life in sustaining global oxygen levels. These oxygen bubbles are m
