I think a good way to think about it is in terms of healthy cycles. PLants create growth from the sun, with help from water and soil. Animals eat plants, excrete, and die. Fungi recycle plants, animals, and their excretions into forms that are reusable for the others to reuse them again, and the cycle repeats. The microbiology is involved and it's more complicated than that, but I wanted people to think about a healthy cycle of rotation in the earth.
