Above Ground Food Webs
In above ground food webs, energy moves from producers (plants) to primary consumers (herbivores) and then to secondary consumers (predators). The phrase, trophic level, refers to the different levels or steps in the energy pathway. In other words, the producers, consumers, and decomposers are the main trophic levels. This chain of energy transferring from one species to another can continue several more times, but eventually ends. At the end of the food chain, decomposers such as bacteria and fungi break down dead plant and animal material into simple nutrients.

Famous quotes containing the words ground, food and/or webs:
“The high that proved too high, the heroic for earth too hard,
The passion that left the ground to lose itself in the sky,
Are music sent up to God by the lover and the bard;
Enough that he heard it once; we shall hear it by and by.”
—Robert Browning (1812–1889)
“The female of the genus homo is economically dependent on the male. He is her food supply.”
—Charlotte Perkins Gilman (1860–1935)
“Sometimes outside beneath a bombers’ moon
You stood alone to watch the searchlights trace
Their careful webs against the boding sky,”
—Edgar Bowers (b. 1924)
