Symbiotic RelationshipsSymbiosis- two species living
togetherhttp://www.youtube.com/watch?v=zSmL2F1t81Q
3 Types of symbiosis:1. Commensalism2. Parasitism3. Mutualism
Type of relationship
Species harmed
Species benefits
Species neutral
CommensalismParasitism
Mutualism
= 1 species
Symbiotic RelationshipsCommensalism-
one species benefits and the other is neither harmed nor helped
Ex. orchids on a treeEpiphytes: 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 xerophyte, air plant.
Symbiotic RelationshipsCommensalism-
one species benefits and the other is neither harmed nor helped
Ex. polar bears and cyanobacteria
Commensalism
Whale & Barnacles
Shark & Remora
Symbiotic RelationshipsParasitism- one species benefits (parasite)
and the other is harmed (host)
• Parasite-Host relationship
Symbiotic RelationshipsParasitism- parasite-hostEx. lampreys, leeches, fleas,ticks, tapeworm,
Not considered predator-prey because goal is not to KILL host
Symbiotic RelationshipsMutualism- beneficial to both
species Cleaner Shrimp &
Fish
Bee & Flower
Mutualism
Egyptian Plover
& Crocodile
Symbiotic RelationshipsMutualism-
beneficial to both species
