Color in a creature on the paper provided, and see the picture you have drawn come to life and move in front of you.

Living things eat and and are eaten by other living things in one shared ecosystem. 

The creatures you draw will multiply if they eat other living things, but they will die and disappear if they do not eat enough, or if they are eaten by other creatures.

The salamanders eat the snakes, the snakes eat the lizards, the lizards eat the frogs, and the frogs eat the butterflies, each one propagating as a result. Likewise, the butterflies multiply in places where flowers grow.

Although flowers will bloom if people stay still, their petals will scatter if people walk around and step on them. The salamanders will die if people step on them too much.

Living creatures spread throughout the world, increasing and decreasing in number. The creatures you have drawn may be increasing somewhere.
