lichen growing on tree bark
Deserts are arid. There is no such thing as a 'semi-arid' desert. Semi-arid regions are steppes or grasslands.
An example of cold desert commensalism is the relationship between lichen and a tree in the Arctic tundra. The lichen benefits from having a stable substrate provided by the tree, while the tree is not significantly affected by the presence of the lichen.

it would be commensalism because the geko needs the desert to live and the desert stays the same!
Mutualism, Commensalism, and Parasitism.
A bird living on the top of a hippo, or a bird living in a cactus is an example of commensalism...:D

Humans getting milk from cows would be an example of commensalism. Commensalism describes a relationship that exists between two organisms in which one organism benefits without harming the other organism.
