  4. Symbiotic Relationships Symbiosis- two speciesliving together http://www.youtube.com/watch?v=zSmL2F1t81Q 3 Types of symbiosis: 1. Commensalism 2. Parasitism 3. Mutualism

  5. = 1 species

  6. 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 xerophyte, air plant.

  7. Symbiotic Relationships Commensalism- one species benefits and the other is neither harmed nor helped Ex. polar bears and cyanobacteria

  8. Commensalism Whale & Barnacles Shark & Remora

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

  10. Symbiotic Relationships Parasitism- parasite-host Ex. lampreys, leeches, fleas, ticks, tapeworm, Not considered predator-prey because goal is not to KILL host

  11. Symbiotic Relationships Mutualism- beneficial to both species Cleaner Shrimp & Fish Bee & Flower
