Ecosphere Concepts and Sustainability

The video, presented by James from the Science Center Singapore, explores the concept of an ecosphere, a sealed ecological system that can sustain itself without external inputs. It explains the components of the ecosphere, including the physical environment and living organisms like algae, shrimps, and bacteria. The video details the interactions within the ecosphere, such as how shrimps, algae, and bacteria contribute to a self-sustaining cycle. The Science Center's ecosphere, sealed since 1993, serves as evidence of long-term sustainability. The video concludes with a call to action for viewers to engage with the channel.
