Biosphärenbaum / Biosphere tree

Stations-ID: L003

Instructions:

This tree has three so-called “hermetospheres.” These are airtight and watertight “bottle gardens” that contain a fully functioning ecosystem. The plants convert CO2 into oxygen. Can you also find the organisms that consume the oxygen and convert it back to CO2? One thing still gets into the sphere despite the seal. Do you know what it is?
