COMMENSALISM
  • Good for me, doesnt bother you!
  • Example Hermit Crab and Snail
  • Remora and Shark
  • A hermit crab lives in shells that are made and
    then abandoned by snails. This neither harms nor
    benefits the snail.
  • A remora attaches themselves to a sharks body.
    They travel with the shark and feed on the left
    over food from the sharks meals. This does not
    hurt or help the shark.

MUTUALISM
Example Ostrich and Gazelle These two animals
feed next to each other in the grasslands. Both
watch for predators and alert each other to
danger. The visual abilities of these two
animals are different so they are able to
identify threats the other animal would not see.

Parasitism
  • Good for me, hurts you!
  • Example Cuckoo and Warbler
  • Deer and Tick
  • A cuckoo may lay its eggs in a warblers nest.
    The cuckoos young will displace the warblers
    young and will be raised by the warbler.
  • A tick feeds on deer blood to the detriment of
    the deer.
