Eczek

Eczek is a fictional term used in speculative biology and world-building to describe a micro-ecosystem component. In the imagined ecology, eczek refers to small, seed-like single-celled organisms that inhabit the surfaces of aquatic plants in temperate wetlands. They are described as 0.2 to 0.5 millimeters in diameter with a translucent, gelatinous body and a faint blue-green bioluminescence visible in low light.

Physically, eczek are depicted as having a simple cell structure that allows rapid growth when nutrients are abundant. Their life cycle is primarily asexual, spreading through budding and colony coalescence. Under drought or nutrient scarcity, they can form dormant cyst-like stages to survive until conditions improve. Some fictional accounts describe a short motile phase, enabling limited movement across plant surfaces to access new nutrient patches.

Ecology and interactions within the fictional system position eczek as both decomposers and a food source. They break down dissolved organic matter on plant surfaces and contribute to nutrient cycling in the wetland microhabitat. They are preyed upon by microinvertebrates and protozoans, while certain mosses and algae in the stories form loose mutualistic associations with eczek, offering attachment sites and protection in exchange for nutrients.

In culture, eczek appear in science fiction and educational simulations as an example of micro-ecosystem dynamics, illustrating how small organisms can influence larger wetland processes. The term is widely used in world-building circles and didactic materials to discuss concepts of adaptation, life cycles, and ecological interactions.
