Symbiosis
A Symbiotic relationship is a close relationship between two species that benefits at least on the
species. The three types of symbiotic relationships are mutualism, commensalism, and
parasitism.
Mutualism- A relationship where both species benefit. The relationship between the saguaro and
the long -eared bat is an example of mutualism.
Commensalism- A relationship where one species benefits and the other species is neither
helped nor harmed. The red-tailed hawks’ interaction with the saguaro is an example of
commensalism.
Parasitism- involves on organism living or on another organism and harming it. The organism
that benefits is called the parasite and the organism it lives inside or on is called the host. An
example of Parasitism is a flea with a dog.
