One example for each type of symbiotic relationship

An example of parasitism in the desert would be a flea on a coyote. The flea gets a delicious meal, but the coyote gets sick. An example of mutualism in the desert would be a mistletoe plant and a phainopepla bird. The phainopepla bird eats berries off the mistletoe plant and digests the seeds, unintentionally laying them in the soil of the desert. This ensures the survival of the mistletoe plant. An example of commensalism in the desert would be a cactus wren building its nest in a cholla cactus. The cactus wren gains a place to protect its young from predators and the cactus in neither helped nor harmed.
