窒素循環のコミック

A comic-style illustration showing the nitrogen cycle in a fun, cartoonish way. Multiple panels showing: 1) nitrogen gas (N2) in the air, 2) lightning fixing nitrogen into the soil, 3) bacteria converting nitrogen into nutrients, 4) plants absorbing nitrogen, 5) animals eating plants, 6) decomposition returning nitrogen to the soil. Colorful, playful comic art style, no text or labels, just visual storytelling.
