About Pond Balance
Pond Balance is a game about food webs. Plants are the producers: they make food from sunlight, and every animal in the pond depends on them in the end. Insects eat the plants, small fish and frogs eat the insects, and the heron eats the fish and frogs. Stock a new pond, run ten seasons, and see which kinds are still alive.
Every animal needs several of the animals below it to live, because energy is used up at each step. That is why a healthy pond has many insects, fewer fish and frogs, and only one or two herons. Take the hunters out and the insects strip the pond of plants. Put them back and the plants return.
Later missions bring an invader, crayfish that nothing in the pond eats yet, and an algae bloom fed by fertiliser washing in from fields. Find the plan that fixes each one, then open the free pond and try anything you like. It is a simple model, not a real pond, but the patterns are the ones scientists see.
