    Q.

    New growth from lichens and moss began to form in a small region of Virginia after a forest fire disturbed, but did not destroy, soil in that area. What type of succession began to form in this area?

    answer choices

    Competitive

    Primary

    Secondary

    Differential

    Ecological succession is changes in the types of species growing in an ecosystem over time

    • Ecosystems typically start with just a few smaller species

    • If allowed to develop, larger and more diverse species move in

  • Question 9
    30 seconds
    Report an issue
    Q.

    The change of an ecosystem over time until a stable stage is reached is called -

    answer choices

    competition

    carry capacity

    succession

    parasitism

  • Slide 10

    Succession begins with a pioneer species and ends with a climax community

    • Pioneer species are the FIRST living things to start growing and are small and grow quickly

    • A climax community is reached when the largest organisms are present and the ecosystem is stable (no longer changing)

  • Question 11
    30 seconds
    Report an issue
    Q.

    The first living thing to grow successfully in a newly formed rock formation are called -

    answer choices

    climax species

    pioneer species

    parasites

    heterotrophs

  • Question 12

    Q.

    Stable, final stage of succession

    answer choices

    adaptation

    pioneer species

    niche

    climax community

  • Slide 13

    Primary succession occurs when an ecosystem starts from NOTHING

    • There is NO SOIL present

    • May occur after a volcano or moving glacier creates new rock

    • The pioneer species are usually bacteria, moss, and lichen, which break down rock to form soil

  • Question 14
    60 seconds
    Report an issue
    Q.

    Primary succession could potentially begin in which of the following environments?

    answer choices

    A field covered with a flow of lava for an extended period of time

    A large plain used for cattle grazing during the past 20 years

    A mountainside that has been clear-cut for logging

    A forest that has been destroyed by two wildfires

  • Slide 15
    Report an issue

    Secondary succession occurs when soil is already present

    • Remember - Secondary HAS Soil!

    • May occur after a flood, fire, or other disaster kills larger species but does not destroy the soil

    • The pioneer species is often grass, but may still include moss, lichen

  • Question 16
    60 seconds
    Report an issue
    Q.

    What is the difference between primary and secondary succession?

    answer choices

    Primary succession already has soil.

    Primary has soil and secondary does not

    soil is present in both

    primary has no soil and secondary has soil

    Q.

    What is an example of primary succession?

    answer choices

    Growth in area where a field has been abandoned

    Growth in an area where a glacier has receded
