"A World in a Jar: the Closed-Loop Ecosphere as a Model of Regenerative Infrastructure

An abundance of sun, of water, of life… energy passes through matter and is continually organized, transformed and transferred through living systems.

Prompt:
Starting from the base components of a closed loop system - energy inputs plus producers, consumers and decomposers - construct a healthy, self-sustaining ecosystem in a closed vessel, permitting solar and
thermal inputs, allowing for minimal gas exchange and water recharge.

A: Document the construction process with diagrams, photos and video.
B: Great a daily/weekly log with organized data tracking:
PH, Ammonia, Nitrate, Nitrite, Temperature, Dissolved Oxygen and CO2 balance

1: Create Soil/Substrate for bacterial Flora (Decomposers)
2: Selected Plants (Producers)
3: Select and phase in snails, shrimp and/or fish befitting the carrying capacity of your ecosystem (Consumers)

Bonus Water Quality Analysis: How far from Papatcton to Potable?
A: Samples from stabilized tanks sent to testing agencies to track water quality and biological and chemical contaminants.
B: Samples from stabilized tanks passed through Lifestraw/LARQ Charcoal and UV filtration then sent for testing."

Two glass aquariums are displayed on a white table. The left aquarium contains clear water with green algae on the surface, a piece of driftwood, and a small rock. The right aquarium has darker water, visible aquatic plants, and a small decorative stone. Above both tanks, LED lights are mounted on the wall, and a white mirror is reflecting the scene. Colorful artwork is partially visible on the table.
