35. Symbiosis Game!!!

36. 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.

37. 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

38. Commensalism

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

40. Commensalism

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

42. Parasitism

43. 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.

44. Mutualism

45. 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.

46. Mutualism

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

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

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

50. Parasitism

51. The human digestive system contains bacteria which aide digestion and vitamin production

52. Mutualism

53. Let’s Tally up the scores!
