Species-001: Treeth

This photosynthetic species appears to be the primary producer on Eth, much like algae was on Old Earth. Treeths are most definitely r -strategists, experiencing huge explosions of population before collapsing and becoming practically absent from an area. Flat planes that exist after floods are converted into “forests” in a few days. Three events lead to the cessation of a bloom. The most common is when the calcium dust drops below a certain level of concentration, starving the organisms. Other times the large clouds of Eth may stay over the area for an extended period of time, preventing treeths from photosynthesising. Rarely, a bloom will coincide with a flood, clearing the area of both treeths and their structures.

Like most producers of Eth, Treeths take in calcium in the atmosphere and convert it into complex ionic molecules, with such molecules remaining in their structures. 

Structure
Although they are unicellular, their structures that they create are extremely noticeable. The structures are composed of complex calcium ionic networks, and resemble coral. Much like tree trunks back on Old Earth, Treeths build these to obtain more light energy or else they are shaded by their competitors’ structures. The treeths themselves stay on top and on the surface of their structures, with the lower and internal part containing no actual treeths. They vary in height depending on the amount of resources at the start of their bloom, sometimes only growing a few centimeters, other times several meters. After the death of the treeths in an area, the structures remain, containing most of the stored energy of the organism.
