Mulch

Mulch grew up in the leaf-litter, in a family of ground-tenders — beetles and worms and quiet fungi who worked the dark layer beneath the forest and never once stood in the sun. The little ones asked, sometimes, if their work mattered, down there where no one looked. Mulch's grandmother showed him a patch of bare, tired dirt where nothing grew, and a patch of dark, crumbly soil rich with broken-down leaves where seedlings pushed up thick and green. "The difference," she said, "is us. The forest eats itself and grows itself, over and over, and we are the turning of it." Mulch understood: the recyclers of the world do the quietest work and the most necessary — without them, the dead would pile up and the soil would starve.

He was grown when he tunneled up to the nature center on the ridge. Terra, the old caretaker, met him at the compost heap and, instead of asking his name, turned over a shovelful of dark, sweet-smelling soil and asked him what had made it.

Mulch touched the crumbly earth with a careful claw. "We did," he said. "The leaf that fell, the apple that dropped, the mouse that died — we broke them down, small and smaller, until they became soil again. That's the nutrients going back to the roots. Energy climbs up the food chain and leaves at the top, but the matter — it comes back down through us, to the beginning, so the grass can grow and the whole thing can start over."

Terra was quiet a moment, then said only, "Then you should stay."

In the compost corner, Mulch shows the kids his patient work. He lifts a rotting log and points out the pale threads of fungus lacing through it, the beetles and worms at their meal. "I am Mulch. My work is decomposition — breaking down the dead so the living can grow." Then he teaches a few things about the recyclers. Nothing is wasted. Every dead leaf and fallen creature becomes food for decomposers, and their leftovers become soil. We close the loop. A food chain looks like it ends at the top — but decomposers bend it back to the bottom, returning the nutrients so it can start again. The soil is alive. Rich soil is full of decomposers hard at work; that's why plants grow there. The unseen work is the most important. And he never once calls the recyclers "the lowly ones." "This work isn't small because it's hidden," he says. "It's the biggest job there is. Every forest, every meadow, every garden runs on it — and nobody claps. That doesn't make it matter less. It makes it matter more."
