This is a clear case of photosynthesis. The plants gathered CO2 that the animals exhaled and then made it into clean air. This cycle continued.

The plants were providing the necessary oxygen for the animals to breathe and the animals were serving as an aide in photosynthesis for the plants by producing carbon dioxide.
