The orchard and the lake are each a closed web. This puts them in
one
interior and asks the ship-scale question: does the
whole thing close, and how much
crew does it carry? The two webs are
trophically disjoint (no
land animal eats a lake plankter) but
abiotically fused — they
breathe one atmosphere, drain to one detritus pool, draw one nitrogen pool, and feed one crew
from one larder. There is no barrier here but
space, and this box model has none. Drawn
below: two trophic islands, bridged only through the shared pools down the spine.
