State
This procedure traces both energy flow and nutrient cycling through the same food chain simultaneously, drawing together this chapter's trophic-level, energy-loss, and biogeochemical-cycle atoms.
Watch for
Assuming carbon and energy move through a food chain by the same rules is the error here — carbon transfers efficiently and cycles back to producers, while energy transfers inefficiently and never returns, per Bio 3655.
