A bottle biosphere (or closed terrarium/aquarium) is a microcosm that demonstrates the principles of ecology, biogeochemical cycles, and energy flow. This guide provides a detailed methodology for creating a fully functional, self-sustaining aquatic ecosystem within a sealed glass container. By balancing primary producers (plants/algae), consumers (invertebrates), and decomposers (bacteria), the biosphere can theoretically sustain itself indefinitely with only light energy input. This paper outlines the biological requirements, step-by-step construction, troubleshooting, and scientific observations of a successful bottle biosphere.
