Unique Symbiosis 

Mutualism is a type of symbiosis relation ship where both organisms benefits each other. The desert bee and cactus are both benefiting each other. The major food resource for desert bee is cactus, and cacti are able to pollinate and reproduce species by desert bee.
 
Commensalism is a symbiosis relationship where one only one side is benefited. Cactus wren is a type of bird which make nest in the tall Cholla cactus so that they can protect them selves and their young offspring, while cactus is not harmed or benefited.
