Photosynthesis and Cellular Respiration Cycle Explained #210114 (License: Personal Use)

The diagram depicts two core biological processes: photosynthesis in chloroplasts (top), where sunlight drives the conversion of carbon dioxide and water into glucose and oxygen, and cellular respiration in mitochondria (bottom), where glucose and oxygen are metabolized to release stored energy (ATP) and heat, regenerating CO₂ and water. Arrows indicate the cyclical exchange of materials between these processes, highlighting ecosystem-level energy flow and matter recycling.

Used in biology education (K-12 and college) on web pages about plant physiology, ecosystems, or energy transfer; matches user intent to understand how life sustains itself through biochemical cycles.
