We’ve been putting together an ecology simulator in Scratch where the user has to decide when to introduce predators in order to bring balance to the ecosystem. Both the insects and predators follow rules:

INSECTS

  • The game will include habitat that insects will feed off

  • Feeding insects gain energy

  • Increased insect feeding will result in a shrinking landscape

  • Reduced insect feeding will result in an expanding landscape

  • Insects can only reproduce if they have sufficient energy

  • Insects die if energy levels reach zero

PREDATORS

  • One predator at a time will be introduced by the player

  • A maximum of three introductions at a time

  • Predators feed off insects to gain energy

  • Predators can only reproduce if they have sufficient energy

  • Predators die if energy levels reach zero
