Questions and Answers

What is the term for the establishment of plant communities in a habitat over a period of time?

  • Primary succession
  • Ecological succession (correct)
  • Secondary succession
  • Seral stages

    • What is the main difference between primary and secondary successions?

  • Primary succession occurs after a volcanic eruption, while secondary succession occurs after a forest fire.
  • Primary succession depends on existing soil, while secondary succession begins on barren land.

    Study Notes

    Ecological Succession

    • Ecological succession refers to the establishment of plant communities in a habitat over time.
    • Primary succession occurs in newly formed or barren habitats, such as after a volcanic eruption, while secondary succession occurs in habitats where a community has been disturbed, such as after a forest fire.
    • Primary succession starts from scratch, with no soil or organisms present, whereas secondary succession starts with a pre-existing soil and some remaining organisms.

    Terrestrial Biomes

    • Not all biomes are mentioned, with tundra being one that is not mentioned.

    Seral Stages

    • Seral stages show the sequence of changes in a community over time during ecological succession.

    Detritivores

    • Detritivores play a crucial role in ecosystems by breaking down organic matter, recycling nutrients, and facilitating nutrient cycling.

    Ecological Concepts

    • The concept of ecological succession relates to the gradual process of change and replacement of species in a community over time.
    • Biodiversity refers to the variety of life in a particular habitat or ecosystem, including genetic, species, and ecological diversity.

    Environmental Awareness

    • Expressing love and respect for fauna and flora within their biomes is essential for promoting conservation and preserving the natural balance of ecosystems.

    Population Growth

    • Rapid population growth can hinder development by straining resources, causing environmental degradation, and leading to social and economic instability.
