Pattern made from four duplicated photos of autumn trees. When the leaves fall and disintegrate they get taken down into the soil by worms or are eaten by insects, or lie as a mulch on the soil surface helping keep it warm. Hedgehogs and other small mammals hide underneath them keeping warm and out of the cold wind.
I do wonder if the soil level would gradually build up as leaves fall year after year. Is this what biomass is? It’s funny what you think about trees….
