Maggots generally doesn't do anything harmful to the human body. Maggots ONLY eat dead flesh and try its best to keep away from clean flesh.

A food chain that includes humans could be grass gets energy from the sun, the grass is eaten by a rabbit, then the rabbit is eaten by a hawk, and then the hawk is eaten by a fox, and then the fox is killed and eaten by a human, and then later the human dies, and is broken down and absorbed by the grass for nutrients and the cycle continues. Another example could be algae gets energy from the sun, the algae is then eaten by a goldfish, and then the goldfish is eaten by a trout, and then the trout is eaten by a bass, and then the bass is eaten by a marlin and then the marlin is eaten by a shark and then the shark is caught and eaten by a human and then later in time the human dies and is broken into nutrients into the ground.
