How does photosynthesis and cellular respiration help green plants survive and other organisms survive?

Photosynthesis allows green plants to convert sunlight, carbon dioxide, and water into glucose and oxygen, providing them with essential energy and food. This process not only sustains the plants but also produces oxygen, which is vital for the survival of aerobic organisms, including animals and humans. Cellular respiration, which occurs in both plants and animals, breaks down glucose to release stored energy for cellular activities. Together, these processes form a crucial cycle that supports life on Earth by linking energy production and consumption among various organisms.
