Sulfur dioxide is a gas that is released from factories and can harm lichens. It can disrupt the photosynthesis process in lichens, leading to their death.

An example of a lichen is the reindeer lichen found in arctic and subarctic regions. This lichen forms a symbiotic relationship between a fungus and an alga, growing on rocks, soil, or tree branches. Reindeer lichen is an important food source for animals like reindeer and caribou.
A lichen is eukaryotic.
an antonym for lichen is swampy.
The gas that is known to harm lichens and is emitted from factories is sulfur dioxide (SO2). This pollutant is a byproduct of burning fossil fuels and industrial processes. Sulfur dioxide can lead to acid rain, which negatively affects ecosystems, including the delicate balance of lichen populations. Lichens are particularly sensitive to air pollution, making them important indicators of environmental health.

There is a lot of lichen growing on the trees.
