Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Define conservation.

    Model answer

    Conservation is the protection and careful management of species and habitats so that they persist for the future.

  2. 2

    Distinguish preservation from conservation.

    Model answer

    Preservation keeps an area untouched and excludes use, while conservation manages use so that the resource is maintained.

  3. 3

    Describe total protection as a conservation strategy.

    Model answer

    An area is closed to access and extraction entirely, so that ecosystems function without human interference.

  4. 4

    Give one strength and one weakness of total protection.

    Model answer

    It gives ecosystems the best chance to recover, but it excludes people who depend on the area and can generate hostility that undermines enforcement.

  5. 5

    What is sustainable use as a conservation approach?

    Model answer

    Sustainable use permits harvesting or visiting at a level the ecosystem can support indefinitely, so local people gain an income from keeping it intact.

  6. 6

    Explain how ecotourism can support conservation.

    Model answer

    Visitors pay to see wildlife in place, which gives the community a direct financial reason to protect the habitat rather than convert it.
