-The soil food web is the community of organisms living all or part of their lives in the soil.
-A food web diagram shows a series of conversions (represented by arrows) of energy and nutrients as
one organism eats another.
-All food webs are fueled by the primary producers: the plants, lichens, moss, photosynthetic bacteria, and algae that use the sun's energy to fix carbon dioxide from the atmosphere.
-Most other soil organisms get energy and carbon by consuming the organic compounds found in plants, other organisms, and waste by-products.
-A few bacteria, called chemoautotrophs, get energy from nitrogen, sulfur, or iron compounds rather than
carbon compounds or the sun.
-As organisms decompose complex materials, or consume other organisms, nutrients are converted from one form to another, and are made available to plants and to other soil organisms.
-All plants depend on the food web for their nutrition.
