Ecosystem

From Creatures Wiki

An ecosystem, in the Creatures series, is the basis of how critters and plants survive together and depend on each other and their surroundings (eg. light and heat cellular automata) in order to survive.

For example, in the Norn Terrarium a dragonfly, stickletrout, the various water plants, and the kingfisher all are in an ecosystem.
