  • Ecological Succession FlipbookThe process of growth, from rock to forest!

    By Liam MassonScience 10, Block 4November 24, 2013

  • Bare Rock

    Lava is cooled and produces bare rock.

    This volcanic rock has no traces of life on it.

    Additional info to include about this stage:-No soil.-No biodiversity.-Zero trophic levels present.-No niches.-No nutrient recycling

    At this early stage, no plants or animals are present.

    These large masses of bare rock came from recently erupted volcanoes on the northern coast of British Columbia. Although it is little known to the general

    public, B.C. is home to a huge area of volcanoes and volcanic activity in the Pacific Ring of Fire.

  • Stage 1: Pioneer Species

    Primary Succession

    Lichen!This previously uninhabited

    rock acts as a home for lichen that soon finds its way almost

    immediately after the rock cools.

    A close-up view of lichen living on rocks, slowly breaking them down into soil.

    -Soil: At this stage the soil is very shallow. Barely any!-Biodiversity? Very low biodiversity. Just lichen.-Trophic levels present: Just one primary producer.-Niches: Very little, simple niches.-Nutrient Recycling? Minimal nutrient recycling.

  • Stage 2: Early Colonizers

    Primary SuccessionSmall organisms,

    plants and insects are present during this


    Insects and plants, such as mosses, begin to grow, die, and decay, adding

    more nutrients to the soil.

    -Soil is still pretty shallow, but contains enough nutrients for small plants and insects.-Low species diversity.-Only two trophic levels.-Few and simple niches.-Simple and little nutrient recycling

    Grasshoppers, Flies and small shrubs like these may be seen in this level of primary succession.

  • Stage 3: OpportunistsPrimary Succession

    Larger shrubs, bushes, and insects, as well as some smaller animals would be seen at this stage of succession.

    As more organisms die and decompose, the soil gains more nutrients and can hold more water. This attracts new

    species and creates larger biodiversity in the area.

    -Soil: Soil is medium depth.-Species diversity? Medium species diversity.-Trophic levels: 2, producers, primary consumers.-Niches? Some. Still quite simple, though.-Nutrient recycling? Medium, effective.

  • Stage 4: Mature Forest/Climax Community

    Primary Succession

    Primary succession is complete!Animals find their way to the ecosystem

    in search of an area with low competition. Coniferous trees germinate

    and shade out the smaller, deciduous trees. A wide diversity of plants and

    animals are introduced and a mature community develops.

    -Soil? Soil is rich and deep.-species diversity? High biodiversity.-trophic levels present? 4 trophic levels: Producers, Primary consumers, Secondary consumers and Tertiary consumers.-niches? Many complex niches.-nutrient recycling? Good, efficient.

  • Pine beetle infestation!Disturbance

    A Pine beetle infestation is introduced into the ecosystem.

    This causes plants and trees to die very quickly. Since the plants that the

    pine beetles kill are primary producers, every trophic level is


    -What is the soil like after the disturbance? After the infected trees die and decompose, the remaining nutrients in the tree are absorbed into the soil.-Species diversity? As animals begin to die out, biodiversity decreases.-Trophic levels: 3:Primary consumers will soon starve, which will kill off the secondary and tertiary consumers.-Niches? Diminishing, simple.-Nutrient recycling? Large amounts of nutrients are released.

  • Secondary Succession

    After a few hundred years, the secondary succession will have

    completed, and a climax community will develop once again..

    Because of the nutrient-rich soil left from the previous

    climax community, the ecological succession can

    easily and quickly take place once again.

    -Soil: Very rich.-Species diversity? Low-Trophic levels: 1, Primary producers.-Niches? Few, simple.-Nutrient recycling? Little nutrient recycling.
