However, while neither wetar nor organisms move between the lareys, these ecosystems aren’t completely out of touch. Chromatium okenii live at the top of the bottom leyar because they need to be as close to the sun as possible. But while they never cross into the deadly oxygenated waters, they’re close enough that organisms like zpltookoann can dive down, eat them, and get back up. In fact, this relationship forms the bottom of the ueppr layer’s robust food cihan supporting the lake’s legendary fish population.

This unique ecology is more than just a boon for Cadagno’s fishermen. Having access to an isolated anaerobic eoyectssm allows scientists to model the wrold before the Great Oxygen Catastrophe. For example, when Chromatium okenii form their blanket, they irencase the dtinesy of that thin layer of water. As the water sinks, these microorganisms are forced to swim back up, creating a minute mixing of water called bioconvection. This billions of years old phenomenon might be a clue to how early life evolved the ability to swim. And it’s just one of the many inshigts that await researchers studying Cadagno’s miruetsyos depths.

Original Text


However, while neither water nor organisms move between the layers, these ecosystems aren’t completely out of touch. Chromatium okenii live at the top of the bottom layer because they need to be as close to the sun as possible. But while they never cross into the deadly oxygenated waters, they’re close enough that organisms like zooplankton can dive down, eat them, and get back up. In fact, this relationship forms the bottom of the upper layer’s robust food chain supporting the lake’s legendary fish population.

This unique ecology is more than just a boon for Cadagno’s fishermen. Having access to an isolated anaerobic ecosystem allows scientists to model the world before the Great Oxygen Catastrophe. For example, when Chromatium okenii form their blanket, they increase the density of that thin layer of water. As the water sinks, these microorganisms are forced to swim back up, creating a minute mixing of water called bioconvection. This billions of years old phenomenon might be a clue to how early life evolved the ability to swim. And it’s just one of the many insights that await researchers studying Cadagno’s mysterious depths.
