Cold Spring Residents

The exhibit introduces how deep-sea cold seep organisms solve their food and drink problems, understand chemoautotrophic microorganisms and processes, the main species and composition of organisms in cold seep ecosystems, and food chain relationships, as well as the adaptive mechanisms of organisms in extreme environments and the exploration of the origin of life. 1. Select the biological type. 2. Click the draw button and create according to the prompts. 3. Click the upload button. Deep sea cold springs are known as the miraculous land of life. In the deep sea without visible light and the conditions for photosynthesis, microorganisms here absorb chemicals leaked from cold spring fluids, obtain energy through their internal chemical reactions, and synthesize organic matter for their own growth. We call it a 'chemoautotrophic microorganism'. When hydrocarbon gases are ejected and reach the seabed, methane oxidizing bacteria and sulfate reducing bacteria participate in the anaerobic methane oxidation reaction between methane and sulfate ions in the cold spring fluid, providing energy for autotrophic organisms.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
