  38. CHANGES IN AN ECOSYSTEM CAUSED BY ANIMALS - INCLUDING HUMANS

  39. This presentation will ask you to THINK – DISCUSS – WRITE But first, here is some background information……

  40. EVERYTHING CHANGES… • Things done by animals cause changes within an ecosystem • These changes can be BENEFICIAL, DETRIMENTAL, or NEUTRAL to other parts of the ecosystem Discuss at your table what you think these three words might mean

  41. BENEFICIAL CHANGES • These changes mean GOOD THINGS for some part of the ecosystem • A change in an ecosystem is BENEFICIAL for some parts of the ecosystem

  42. DETRIMENTAL CHANGES • These changes mean BAD THINGS for some part of the ecosystem • Some changes are DETRIMENTAL for some parts of the ecosystem

  43. These changes mean NEITHER good things nor bad things for some part of the ecosystem Some changes are NEUTRAL for some parts of the ecosystem – these changes have NO EFFCT on certain parts of an ecosystem NEUTRAL CHANGES

  44. Let’s look at some examples… Can you name this animal?

  45. This animal is a BEAVER DISCUSS AT YOUR TABLE – What are some things you know about the beaver?

  46. BEAVERS BUILD DAMS Beavers live in rivers or streams. They build dams which stop the flow of the water.

  47. THINK & DISCUSS How did the beaver building a dam change the ecosystem? How are these changes BENEFICIAL? DETRIMENTAL? NEUTRAL? After discussion, we will complete our note sheet together.

  48. Here’s another example…. Can you name this animal?

  49. This animal is an EARTHWORM DISCUSS AT YOUR TABLE – What are some things you know about the earthworm?
