Symbiosis describes close interactions between two or more different species, since the desert is a biome that has little resources needed to survive not many symbiotic relationships are in the desert. Mutualism, Commensalism, and Parasitism are symbiotic relationships some examples of these are:
Mutualism- bats eat nectar from cacti while pollinating Commensalism- gopher snakes use abandoned rodent holes as homes Parasitism- a flea drinks the blood of a coyote
