  7. Two or more species cannot share the same niche

  8. Video to introduce symbiosis

  9. Symbiosis -a close relationship between two organisms in which at least one organism benefits

  10. Commensalism

  11. one organism benefits and the other is not harmed

  12. Mutualism

  13. Mutualism -both organisms benefit

  22. Symbiosis Game!!!

  23. Rules: You will be given an interaction between two living organisms. With your team quietly discuss what type of symbiosis you think it is: commensalism, parasitism, or mutualism. When time is up you will be ask to hold up your card to show what type you think it is. Each correct answer gets your team one point.

  24. The gall insect lays eggs in an oak tree, causing a lump that isn’t harmful to the tree.  It also gets shelter and food from the tree

  25. Commensalism

  26. The bison stirs up insects in the grass, which the cowbird eats

  27. Commensalism

  28. The cowbird lays eggs in other birds’ nests and the cowbird chicks push out the host eggs and eat the parents’ food

  29. Parasitism

  30. Morel mushrooms help the tree roots absorb water and minerals, and sugar and starches are absorbed by the mushroom.  When the tree dies the mushroom produces spores to reproduce.

  31. Mutualism

  32. The monarch butterfly drinks nectar and lays eggs on milkweed.  The monarch larvae eat the milkweed leaves and obtain the leaves’ poisonous chemical which prevents predators from eating them, the monarch also pollinates the milkweed.

  33. Mutualism

  34. Grape vines grow up the trunk of the ash tree to get more light and space

  35. Commensalism, but some other vines kill the tree which is parasitism

  36. Freshwater mussels lay larvae on fish which irritate the fish’s scales

  37. Parasitism
