Since fungi are heterotrophs and therefore cannot make their own food, they must rely on autotrophs that photosynthesize the suns energy to produce nutrients necessary for growth and reproduction. The rhizines are black and unbranched. The lichen's body is made of fungal In addition to thriving on bountiful rock and wood surfaces, the chemical shield screens sunlight to protect the green algal energy source and guard against assault by microbes and mammals. Lichens are very particular organisms, resulting in a stable symbiotic association between a fungus and an alga or a cyanobacterium. While this union must have occurred at least once for any lichen to exist, a singular rare event in the millions of years of geologic time is not unusual. Brodo claims rock-dwelling Flavoparmelia are typically broader-lobed and more wrinkly1. [6] The function of yeast fungi is not yet known. Working to make it easier for people to live their healthiest lives is central to who we are. Their persistence is testimony to the lichen lifestyle, one of the natural worlds wonders.
