Question

Quizplus · Accepted Answer

The food chain concept illustrates the energy transfer from one trophic level to the next, with a significant amount of energy lost at each step. To produce one kilogram of weight gain in a human, who is several trophic levels above plankton, it takes about 1,000 kilograms of plankton. This is due to the inefficiency of energy transfer between trophic levels, where approximately 90% of the energy is lost at each step, primarily as heat.
