Sound is the same three traces the chart draws, as three voices. Everything is normalised to −20 dBFS RMS and can never exceed −9 dBFS peak, so it stays at one comfortable level however the run goes. Hear the run in the lab plays the whole history in nine seconds.

The chart spans the whole run, not a recent window. When its buffer fills it halves itself and samples half as often, so it always reaches back to tick zero.

Inside this world

Energy is conserved: photosynthesis is the only inflow, metabolic heat the only outflow, and everything else is a transfer. Body size, diet, sensing range and even plasticity are genes under selection, so trophic levels emerge rather than being declared.
