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.

“And he gave it for his opinion, that whoever could make two ears of corn, or two blades of grass, to grow upon a spot of ground where only one grew before, would deserve better of mankind, and do more essential service to his country, than the whole race of politicians put together.”

“To give money to a sufferer is only a come-off. It is only a postponement of the real payment, a bribe paid for silence, a credit system in which a paper promise to pay answers for the time instead of liquidation. We owe to man higher succors than food and fire. We owe to man.”
—Ralph Waldo Emerson (1803–1882)
“You sit around here and you spin your little webs and you think the whole world revolves around you and your money. Well it doesn’t, Mr. Potter. In the whole vast configuration of things I’d say you were nothing but a scurvy little spider.”
—Frances Goodrich (1891–1984)
