    • expanding towns
    • increasing land use

  6. Which conservation method specifically targets rare ecosystems?

    • landfill disposal
    • deforestation

    • urban expansion

  7. What do hedgerows help restore on single-crop farms?

    • wildlife habitat
    • pesticide resistance
    • carbon emissions
    • soil toxicity

  8. Which human action is a negative interaction in an ecosystem?

    • landfill dumping
    • captive breeding
    • habitat regeneration
    • field margins

  9. Separating paper and glass for reuse is an example of what?

    • landfill dumping
    • recycling resources
    • habitat destruction
    • deforestation

  10. Breeding a rare bird in captivity for release is which programme?

    • waste disposal
    • habitat destruction
    • crop monoculture
    • captive breeding

  11. Leaving strips of wild flowers at field edges is known as what?

    • urban zones
    • deforested areas
    • landfill sites
    • field margins

  12. Which government action helps reduce carbon dioxide emissions and protect biodiversity?

    • Increasing landfill
    • Reducing deforestation
    • Removing hedgerows
    • Expanding urban areas

  13. What is a key conflicting pressure when trying to maintain biodiversity?

    • Nature reserves
    • Food production
    • Breeding programmes
    • Seed banks

  14. What must be provided when releasing animals from a breeding programme into the wild?

    • Daily feeding
    • Protected habitat
    • Artificial shelter
    • Domestic cages

  15. What is a common trade-off when implementing conservation schemes?

    • Zero environmental impact
    • Instant ecosystem recovery
    • Eliminated food supply
    • High financial costs

  16. Removing farm hedgerows to increase crop area results in what trade-off?

    • Lower food yield
    • Reduced wildlife habitat
    • Increased biodiversity
    • Higher soil fertility

  17. How does recycling positively impact biodiversity compared to landfill?

    • Raises global temperatures
    • Increases quarrying
    • Destroys forest habitats
    • Reduces land use

  18. Why are captive breeding programmes alone insufficient for saving endangered species?

    • animals refuse to eat
    • habitats are missing
    • breeding rates are zero
    • funding is always illegal

  19. Which measure reduces waste pollution and protects land biodiversity?

    • Incinerating plastics
    • Landfill dumping
    • Deep well injection
    • Recycling resources

  20. Which human activity is an example of a positive interaction with an ecosystem?

    • Protecting rare habitats
    • Draining wetlands
    • Clear-cutting forests
    • Overfishing oceans
