ナショナルジオグラフィックさんのインスタグラム写真 - (ナショナルジオグラフィックInstagram)「Photos by Keith Ladzinski @ladzinski / If you’ve ever wondered why plants change color in the autumn, here’s a brief explanation: As the days get shorter, leaves stop producing chlorophyll, a pigment triggered by sunlight that helps the leaf absorb energy through photosynthesis. Once chlorophyll production ceases, the green color fades and the pigment xanthophyll begins to show—typically in the yellow, orange, and red spectrum. These colors are a clear signal that the flora is moving into winter hibernation. This carousel was  photographed in a 30-foot radius in South Bend, Indiana.
