Man-made closed ecological systems which were created to sustain human life include Biosphere 2, MELiSSA, and the BIOS-1, BIOS-2, and BIOS-3 projects. [ 4 ] Bottle gardens and aquarium ecospheres are partially or fully enclosed glass containers that are self-sustaining closed ecosystems that can be made or purchased.
They talked about how they were going to make vibrating eggs but they took a different route.In the paper Hanson stated that the composition of the closed ecosystems he created was 50% distilled water brought to a salinity of 11 parts per thousand by the addition of "Instant Ocean", 50% air, algae collected from the ponds of Halocaridina rubra ...
Mini ecosystems are the latest trend on the garden side of TikTok. Follow these steps to make an easy closed terrarium. The Latest From #PlantTok Are Mini Ecosystems—Here's How to Make One
This bottle with a lime pothos (Epipremnum aureum) has not been opened or watered since the plant was placed in it several months previously.A bottle garden has the essential requirements of soil, water, and light for the survival of plants and other organisms that are housed in it, as well as a reservoir of water, as water is trapped inside the bottle and unable to evaporate.
Keeping the terrarium sealed allows for circulation of water, making the terrarium self-sufficient. The terrarium may be opened once a week, allowing evaporation of excess moisture from the air and walls of the container, to prevent growth of mold or algae , which may damage plants and discolor the sides of the terrarium.

A tomato greenhouse in the Netherlands. The advantage of mesocosm studies is that environmental gradients of interest (e.g., warming temperatures) can be controlled or combined to separate and understand the underlying mechanism(s) affecting the growth or survival of species, populations or communities of interest.
The ecosystem conditions applying at a typical pond edge can be quite different from those further from shore. Extremely space-limited water ecosystems can be found in, for example, the water collected in bromeliad leaf bases and the "pitchers" of Nepenthes .
After the column is sealed tightly the anaerobic bacteria will develop first, including Clostridium spp. These anaerobic bacteria will consume the cellulose as an energy source. Once this commences they create CO 2 that is used by other bacteria and thus the cycle begins. Eventually colour layers of different bacteria will appear in the column.
