Describe the ecosystem on the lifeboat?

The ecosystem on a lifeboat is typically minimal and highly dependent on the limited resources available. It may consist of a small number of microorganisms, such as bacteria and algae, that can survive in the confined environment, along with any remaining food sources or waste products. The interactions among these organisms can lead to a fragile balance, where any significant change in conditions—like temperature or available nutrients—can disrupt the ecosystem. In such a closed system, human presence and activities also significantly impact the ecosystem's dynamics.
