This film shows how and why the animals which inhabit a pond are dependent one on another for their survival. We see the minnow in pursuit of water fleas and a stickleback seeking worms to satisfy his need of fuel. Carbon-dioxide, we are reminded, is essential for the growth of the green plants and the oxygen they release for the breathing of the animal population of the pond.
