There are 3 species of organisms. Plants (but not really) that range in 3 types that do the exact same thing. `Green are herbivorous, and red are carnivores. Plants grow automatically, herbivores eat plants to spawn new herbivores, and carnivores eat herbivores to spawn near ones. They all die after a certain time. Apex predator can die by only hunger. It has a chance of eating the carnivore or herbivore when touching it
The ecosystem dies a lot trust. You cannot affect the game from the outside.
