Ecosystems & Food Webs

The one idea that wires every living thing in a place together — who-eats-what, all running on energy from the Sun. From why a hawk is rare, all the way to reasoning backwards from a rabbit plague to its missing predator. Four short steps, each with its own toy to play with.

1 Where it comes fromEverything alive is connected by who-eats-what. Drag organisms onto a canvas and draw the feeding arrows yourself. 2 How to do itThe four roles, trophic levels, and the energy pyramid that explains why top predators are so rare. 3 Where it gets trickyArrows point at the eater, removing one species ripples everywhere, and decomposers are the unsung heroes. 4 Out in the wildDingoes, cane toads and rabbit plagues — and reasoning backwards from a population crash.
