  • Why Do Forests Have Layers?

    Why Do Forests Have Layers?
    Jun 26 2026
    A walk through the forest reveals something surprising: plants and animals stack themselves into distinct layers from the treetops all the way down to the soil. Each layer gets different amounts of sunlight, rain, and wind, creating unique little worlds where different creatures make their homes. The episode traces how light drives this vertical architecture, why some plants race to the top while others thrive in the shade, and how decomposers on the forest floor recycle everything back into nutrients that feed the whole system.

It also follows the fallen leaves to the forest floor, where decomposers break them down into nutrients that feed the next generation of growth.
