Symbiotic Relationships Commensalism- one species benefits and the other is neither harmed nor helped Ex. orchids on a tree Epiphytes: A plant, such as a tropical orchid or a bromeliad, that grows on another plant upon which it depends for mechanical support but not for nutrients. Also called aerophyte, air plant.

Symbiotic Relationships Commensalism- one species benefits and the other is neither harmed nor helped Ex. polar bears and cyanobacteria You can see here that this polar bear is no longer white.

Symbiotic Relationships Parasitism- one species benefits (parasite) and the other is harmed (host) Parasite-Host relationship

Symbiotic Relationships Parasitism- parasite-host Ex. lampreys, leeches, fleas, ticks,tapeworm

Symbiotic Relationships Mutualism- beneficial to both species Ex. cleaning birds and cleaner shrimp The Egyptian plover takes insects from the backs of buffaloes, giraffes and rhinos. The plover has also been observed taking leeches from the open mouths of crocodiles! In this association the plover receives a supply of food and the other animal rids itself of unwelcome pests

Symbiotic Relationships Mutualism- beneficial to both species Ex. lichen The Egyptian plover takes insects from the backs of buffaloes, giraffes and rhinos. The plover has also been observed taking leeches from the open mouths of crocodiles! In this association the plover receives a supply of food and the other animal rids itself of unwelcome pests

In all symbiotic relationships one of the species (organisms) is always benefitted from the relationship, but what happens to the other species (organism)? Type of relationship Species harmed Species benefits Species uneffected Commensalism Parasitism Mutualism

What symbiotic relationship is this? Clown Fish & Anemone This clown fish swims in the anemone and gets protection, since its predators will get stung. The anemone is unaffected. What symbiotic relationship is this? commensalism

What symbiotic relationship is this? Antelope & Ox Bird This ox bird hangs out on the antelope and gets a delicious meal of bugs living on the antelope. The antelope gets rid of parasites. What symbiotic relationship is this? mutualism
