In nature, decomposers often use the fallen leaves and tissues of a plant as a food source. In turn, the fecal matter of these organisms is usually one of the main nutrient sources for plants. Decomposers, such as some species of microscopic insects, nitrogen-fixing bacteria, and fungus contribute to the nutrient cycle by uptaking the waste material and converting it directly into pure nutrients for plants.
at Pan’s lab, we grow our own colony of decomposers. They include two species of microscopic insects that specialize in nitrogen fixation, nutrient-fixing bacteria, and also different forms of fungus. According to the plants’ origins and their physiology, we carefully add these decomposers into ecojars with the correct portion and combination. These decomposers cannot escape and they cannot survive outside of established
environment of the ecojar.
gas cycle: The gas cycle is derived from the photosynthesis and cellular respiration formulas.
during the day, plants uptake carbon dioxide and water to make organic matter and oxygen gas; at night, this process is reversed. these two opposite processes allow carbon dioxide and oxygen to be reused.
at Pan’s lab, we calibrate the gas cycle by using leaf litters and other organic chemicals, allowing the gases to be perpetually recycled.
Hydrological Cycle: Also known as the water cycle. In nature, water flows from the mountains into the ocean. Clouds are condensations of water, moving water back to its source.
At Pan’s lab, we are able to simulate this process through careful calibration and repeated experimentation.
During the day, the heat from the sun or artificial lighting drives water out of soil and condensation forms on the walls of the terrarium. At night, the temperature drops and the condensation drips down to form a simulated miniature rainfall. I carefully calibrate the water to make sure the condensation does not block the view.
