Plants make sugar through a process called photosynthesis (光合作用).This happens when a plant receiving light changes water and carbon dioxide into food. Much of the sugar is pumped down through the roots. There, it is turned into sugar-based food and released into the soil. That is done ...
As incoming sunlight dimmed, photosynthesis waned and the base of the food chain on land and in the ocean collapsed, bringing down the dinosaurs and many other animals. Meanwhile, the airborne sulfuric acid led to lethal acid rain that rained for days following the impact, killing countless ...
