Five Days Inside a Sealed Ecosystem

Five days into sealing the ecosystem, miniBIOTA enters one of its first serious closed-system tests: whether the connected food web can keep oxygen and balance stable with no additions or removals. The video follows the system after major lake corrections, especially the removal of most Creeping Primrose Willow, and frames the sealed run as a shift from asking whether miniBIOTA could work to observing how it behaves as a biosphere.
