Fungi
Fungi are very difficult to observe. What we call a mushroom is only the tip of the iceberg of a much bigger and essentially invisible organism that lives most of its life underground. The mushroom is the ―fruiting body of a subterranean network of microscopic hyphae, improbably long root-like cells that thread themselves through the soil like neurons. "Fungi, lacking chlorophyll, differ from plants in that they can't manufacture food energy from the sun. Like animals they feed on organic matter made by plants or by plant eaters. The talent of fungi for decomposing and recycling organic matter is what makes them indispensable, not only to trees but to all life on earth. If the soil is the earth's stomach, fungi supply its digestive enzymes - literally. Without fungi to break things down the earth would long ago have suffocated beneath a blanket of organic matter created by plants the dead would pile up without end, the carbon cycle would cease to function, and living things would run out of things to eat.
