    15. 15. Biotic and Abiotic Factors16Within an ecosystem are its living andnon-living components.
    16. 16. Biotic and Abiotic Factors17These components can be separatedinto biotic and abiotic factors.
    17. 17. Biotic and Abiotic Factors18Biotic factors are living things, theirremains, and physical featuresassociated with their activites.
    18. 18. Biotic and Abiotic Factors19Abiotic factors are non-livingphysical and chemical componentsof an ecosystem.

    41. 41. 42Ecosystem Review – DO NOT COPYWhat are the abiotic and bioticfeatures of the boreal forest?
    42. 42. 43Ecosystem Review – DO NOT COPYWhat are the abiotic and bioticfeatures of the boreal forest?Abiotic features:•Long, cold winter season•Warm summers•Moderate rainfall•Much of the precipitation is snow•Snow insulates and protects groundspecies
    43. 43. 44Ecosystem Review – DO NOT COPYWhat are the abiotic and bioticfeatures of the boreal forest?Biotic features:•Few species•Mainly black spruce forest and bogs•Black bears, red squirrels, and moose•Many biting flies•Reduced ecosystem productivity dueto short growing season
    44. 44. 45Ecosystem Review – DO NOT COPYWhat are the abiotic and bioticfeatures of a beaver pond?
    45. 45. 46Ecosystem Review – DO NOT COPYWhat are the abiotic and bioticfeatures of a beaver pond?Abiotic features:•Shallow water•Warm water in summer, ice-covered in winter•Temporary, but lasting years todecades•May break, causing floodingdownsteam
    46. 46. 47What are the abiotic and bioticfeatures of a beaver pond?Biotic features:•Community ofplants, fish, frogs, turtles, insects,and beavers•Surrounding forest is a foodsupply for the beavers•Flooding kills trees, which arethen used by species as food orshelter.Ecosystem Review – DO NOT COPY
    47. 47. Sustainability48What does it mean to sustain something?
    48. 48. Sustainability49A sustainable ecosystem is an ecosystem thatmaintains itself through natural ecological processes.
    49. 49. Sustainability50It can stay the same and preserve itself over a longperiod of time.
    50. 50. Are we living sustainably?Sustainability
    51. 51. 52What are some ways humans are making some ecosystemsunsustainable?Sustainability
    52. 52. Sustainability53Examples:LitteringPollutingLogging
    53. 53. Sustainability54Humans can also make artificialecosystems which are notsustainable. We must maintainthem ourselves.
    54. 54. SustainabilityWe are all connected to the ecosystems we live inand they influence many aspects of our lives.
    55. 55. Sustainability56Ecosystems provide wealth for many people, andcan affect our health and our moods.
    56. 56. Sustainability57What are 2 ways that ecosystems affect our:•Wealth?•Health?•Moods?
    57. 57. Sustainability58What are 2 ways ecosystems affect our:•Wealth?- Wood and forestry industry.- Mining industries.•Health?-People living in smoggy cities more likely to have asthma.-People that live at high altitudes breathe thinner air and havemore red blood cells.•Moods?Some ecosystems experience longer winters or more rainy days:- Seasonal Affective Disorder (SAD): depression caused byincreasing dark hours and drop in temperature that comes withfall/winter.- Rainy day “blahs” versus bright sunny days.
