The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals.
Food webs describe the transfer of energy between species in an ecosystem. While a food chain examines one, linear, energy pathway through an ecosystem, a food web is more complex and illustrates all of the potential pathways. Much of this transferred energy comes from the sun. Plants use the sun’s energy to convert inorganic compounds into energy-rich, organic compounds, turning carbon dioxide and minerals into plant material by photosynthesis. Plants are called autotrophs because they make their own energy; they are also called producers because they produce energy available for other organisms to eat. Heterotrophs are consumers that cannot make their own food. In order to obtain energy they eat plants or other heterotrophs.

Famous quotes containing the words soil, food and/or web:
“Have you seen but a bright lily grow
Before rude hands have touch’d it?
Have you mark’d but the fall of the snow
Before the soil hath smutch’d it?
Have you felt the wool of the beaver,
Or swan’s down ever?
Or have smelt of the bud of the brier,
Or the nard in the fire?
Or have tasted the bag of the bee?
O so white, O so soft, O so sweet is she!”
—Ben Jonson (1572–1637)
“Taking food alone tends to make one hard and coarse. Those accustomed to it must lead a Spartan life if they are not to go downhill. Hermits have observed, if for only this reason, a frugal diet. For it is only in company that eating is done justice; food must be divided and distributed if it is to be well received.”
—Walter Benjamin (1892–1940)
“Ye whose clay-cold heads and luke-warm hearts can argue down or mask your passions—tell me, what trespass is it that man should have them?... If nature has so wove her web of kindness, that some threads of love and desire are entangled with the piece—must the whole web be rent in drawing them out?”
—Laurence Sterne (1713–1768)
