How to play
Select food, then the organism that eats it. Arrows show energy moving from food to eater. Read each organism’s diet clue, connect all six relationships in this simplified Gulf of Maine web, then check. Select a connected pair again to remove its arrow. Undo and hint are available. After completion, choose an organism to trace a path from phytoplankton, or temporarily remove it and see which nodes have no remaining shown path. This explores only the displayed relationships; it does not predict population sizes, starvation or extinction. Tap or use Tab and Enter. Progress stays in this browser.
