Photosynthesis and respiration are fundamental processes for life on Earth. Photosynthesis, primarily conducted by plants, converts sunlight into energy, producing oxygen and organic compounds essential for the survival of most organisms. Respiration, whether aerobic or anaerobic, is crucial for breaking down these organic compounds to release energy needed for cellular functions. Without respiration, life as we know it would not exist. Furthermore, photosynthesis serves as the primary energy source for ecosystems, supporting both plant and animal life. The interdependence of these processes underscores their importance in maintaining life on the planet.
