  1. Interactions

  2. Predation • The capturing of prey as a means of maintaining life • One organism benefits • One organism is killed

  3. Parasitism A tomato hornworm is covered with cocoons of pupating braconid wasps One organism (the parasite) benefits and the other (the host) is harmed, but is still alive

  4. Parasitism • Can be considered a special case of predation • Because the parasite needs the host to remain alive, it is typically advantageous for the parasite NOT to kill its host

  5. Lampreys are Parasites

  6. Mutualism • Mutualism is any relationship between two species of organisms that benefits both species.

  7. Examples of Mutualism • Pollination • Seed Dispersal • Lichens

  8. Commensalism • Relationship between two species where one species benefits from the relationship and the second species is unaffected

  9. Examples of Commensalism • Barnacles and Bird Nests
