Photosynthesis and Respiration Cycle in Plants - Educational Diagram #2173180 (License: Personal Use)

This diagram depicts the interconnected processes of photosynthesis (daytime), where a plant uses sunlight, water, and CO₂ to produce food and release oxygen, and respiration (day and night), where the plant consumes oxygen and releases CO₂. It also illustrates how decaying organic material enriches soil with nutrients and water, which roots absorb to sustain growth.

Used in biology education, science textbooks, or environmental science web pages to explain ecosystem energy flow and plant physiology; matches user intent for learning basic botany or ecological cycles.
