Birds and bugs wander randomly around the landscape. Each step costs both animals energy and they must consume a food source (bugs must eat grass and birds must eat bugs & the invaders) to replenish their energy - when they run out of energy they die. To allow the population to continue, each bird or bug must have enough energy to have a litter of offspring and the offspring and parent split the energy amongst themselves. Grass grows at a fixed rate, and when it is eaten, a fixed amount of grass energy is deducted from the patch (square) where the grass was eaten. Invasive species (mice) can be introduced to this ecosystem as well. The mice are indirect competitors of the bugs. They also eat grass. They reproduce following the same rules as bugs. The eating behavior of the mice and the bugs can be adjusted. false 2026-02-28T16:04:20Z 2461100.1696759 BugHuntPredator
