  1. 3.3 Community Interactions

  2. Standards • Anchor: BIO.B.4.2 Describe interactions & relationships in an ecosystem • BIO.4.2.2: Describe biotic interactions in an ecosystem

  3. Ecology • Organisms interact with each other when share same habitat or niche • Types of interactions: • Competition • Predator/prey • Symbiosis: two organisms in close, constant contact • Commensalism • Mutualism • Parasitism

  4. Ecology • Community Interactions • Competition: organisms attempt to use a resource at the same time in the same place • Resource could be mate, food, territory, etc.

  5. Ecology • Predation: one organism (predator) captures and kills another organism (prey) • Ex: lion hunts and kills wildebeest http://dsc.discovery.com/tv-shows/life/videos/komodo-dragons-hunt-buffalo.htm

  6. Ecology • Symbiosis: relationship in which two species live closely together • Mutualism: both species benefit from the relationship • Ex: Flowers depend on bees to pollinate them • Flowers  reproduce • Bees  getfood

  7. Ecology • Symbiosis • Mutualism: • Ex: Birds on back of buffalo • Birds food • Buffalo get cleaned/protection from parasites

  8. Ecology • Symbiosis • Commensalism: one species benefits; one is unaffected • Ex: Barnacles attaching to whale • Barnacle  filters water to get food • Whale  unaffected

  9. Ecology • Symbiosis • Commensalism: • Ex: Orchids growing up trees in Rain Forest • Orchids  more sunlight • Tree  unaffected

  10. Ecology • Symbiosis • Parasitism: one species (parasite) feeds on but doesn’t kill another (host) • Ex: tick (parasite) on a deer (host) • Ex: tapeworms (parasite) in animals intestines (host)
